Opening claim text (preview).
What is claimed is: 1 . A compound, which is Compound 1 having the structure: or a pharmaceutically acceptable salt thereof. 2 . The compound of claim 1 , which is Compound 1a having the structure: or a pharmaceutically acceptable salt thereof. 3 . The compound of claim 1 , which is Compound 1b having the structure: or a pharmaceutically acceptable salt thereof. 4 . The compound of claim 1 , which is a hydrochloric acid salt. 5 . A pharmaceutical composition comprising the compound of claim 1 , or a pharmaceutically acceptable salt thereof, and at least one pharmaceutically acceptable carrier. 6 . A method of modulating S1P receptor activity, said method comprising contacting a compound of claim 1 , or a pharmaceutically acceptable salt thereof, with an S1P receptor. 7 . The method of claim 6 , wherein the S1P is S1P5. 8 . The method of claim 6 , wherein the contacting comprises administering the compound to a patient. 9 . A method of treating a disease or disorder associated with S1P5, said method comprising administering to a patient in need thereof a therapeutically effective amount of a compound of claim 1 , or a pharmaceutically acceptable salt thereof. 10 . A method of treating a CNS disorder in a patient in need thereof, said method comprising administering to the patient a therapeutically effective amount of the compound of claim 1 , or a pharmaceutically acceptable salt thereof. 11 . The method of claim 10 , wherein the CNS disorder is Alzheimer's disease, or vascular dementia. 12 . The method of claim 10 , wherein the CNS disorder is Niemann-Pick disease. 13 . The method of claim 10 , wherein the CNS disorder is Niemann-Pick type C disease. 14 . The method of claim 10 , wherein the CNS disorder is cognitive deficits in schizophrenia, obsessive-compulsive behavior, major depression, autism, multiple sclerosis, or pain. 15 . The method of claim 10 , wherein the CNS disorder is a cognitive disorder. 16 . The method of claim 15 , wherein the cognitive disorder is age-related cognitive decline. 17 . A process of preparing Compound 1 having the structure: or a pharmaceutically acceptable salt thereof, comprising: (a) reacting Compound G, or a salt thereof: with a compound having the structure: to prepare Compound H, or a salt thereof: and (b) reacting Compound H, or a salt thereof, with hydroxide followed by treatment with an acid to form Compound 1. 18 . The process of claim 17 wherein Compound G, or a salt thereof, is prepared by reacting Compound D, or a salt thereof: with CH 2 ═CH—C(O)OEt. 19 . The process of claim 18 wherein Compound D is prepared by reacting Compound C, or a salt thereof: with a protic acid. 20 . The process of claim 19 wherein Compound C, or a salt thereof, is prepared by reacting Compound B: with 1,2-ethanolamine. 21 . The process of claim 20 wherein Compound B is prepared by reacting Compound A: with trimethylsulfonium bromide. 22 . A compound, which is Compound 1, prepared by the process of claim 17 .
