First claim
Opening claim text (preview).
What is claimed is: 1. A process for the preparation of secondary amine (1d) which comprises reacting N-(3-chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)acetamide (1c) with a suitable reducing agent in the presence of an acid. 2. The process of claim 1 , wherein the reducing agent is a hydride source. 3. The process of claim 1 , wherein the reducing agent is sodium borohydride. 4. The process of claim 1 , wherein the acid is a Brønsted acid. 5. The process of claim 1 , wherein the acid is a Lewis acid. 6. The process of claim 5 , wherein the Lewis acid is borontrifluoride etherate. 7. The process of claim 2 , wherein the acid is a Lewis acid. 8. The process of claim 7 , wherein the Lewis acid is borontrifluoride etherate. 9. The process of claim 3 , wherein the acid is a Lewis acid. 10. The process of claim 9 , wherein the Lewis acid is borontrifluoride etherate.
