1 - 9 . (canceled) 10 . A method of treating a liver malignant tumor, comprising the step of administering to a subject at least one compound selected from the group consisting of compounds represented by formulas (1), a salt thereof, or a solvate thereof: wherein R 1 , R 2 , and R 4 are the same or different and each represent H, halogen, nitro, cyano, OH, optionally substituted C 1-6 alkyl, optionally substituted C 2-6 alkenyl, optionally substituted C 1-6 alkoxy, aryl, or heteroaryl; R 3 represents H, optionally substituted C 1-6 alkyl, or optionally substituted C 2-6 alkenyl; m represents an integer of any of 1 to 4; n is an integer of any of 1 to 3; and p represents an integer of any of 1 to 5. 11 . The method of treating a liver malignant tumor according to claim 10 , wherein the R 1 , R 2 , and R 4 are the same or different and each represent H, halogen, nitro, cyano, OH, C 1-6 alkyl, C 1-6 halogenoalkyl, C 1-6 hydroxyalkyl, C 1-6 alkylamino, C 1-6 alkoxy, C 1-6 halogenoalkoxy, C 1-6 hydroxyalkoxy, or C 1-6 alkoxyamino, or C 1-6 alkoxy-substituted C 1-6 alkoxy, C 1-6 alkoxyphenyl-substituted C 1-6 alkoxy, (trialkylsiloxy) C 1-6 alkyl, or (alkyl diphenyl siloxy) C 1-6 alkyl; and the R 3 are H. 12 . The method of treating a liver malignant tumor according to claim 10 , wherein in the formula (1), the R 1 , R 2 , and R 3 are each H, the R 4 is at position 4 and represents H, F, Cl, nitro, OH, CH 2 OH, methoxy, methoxymethoxy, tert-butyl dimethyl siloxymethyl, or 4-methoxybenzyloxy. 13 . The method of treating liver malignant tumor according to claim 12 , wherein R 4 represents H. 14 . The method of treating liver malignant tumor according to claim 12 , wherein R 4 represents F. 15 .
