Title compds. (I, R1 = H, lower alky1, Ph; R2 = H, C1, methoxy; R3 is H or methoxy and forms methylenedioxy or ethylenediox group with R2; R4,R5 = H, lower alky1; R6 = H, lower alkoxy; R7 is lower alkoxy or forms methylenedioxy or ethylenedioxy with R6; X = carbony1; n = 2,3), useful as heart rate decreasing agent, were prepd. Thus, benzylhalide(II, Hal = C1, Br, iodo) was treated with amine(III) and the 1-amino-phthalimidine was hydrolyzed followed by alkylation to give I.
