Abstract
The derivs. are of formula (I) in which R1 and R2 are H, OH, halogen, NO2, NH2, 2-5C acylamino, 1-4C alkyl, CHO, CH2OH, CHOH-1-3C alkyl, 1-4C alkoxy or alkylthio, 1-4C alkylsulphinyl or alkylsulphonyl, N-substd. heterocycle, opt. substd. phenyl, or phenyl sulphonamido, or R1 and R2 together form a 3-5C alkylene bridge, R3 is H, 1-4C alkyl or 2-4C alkenyl, is (CH2)nNR4R4, in which R4 is 1-4C alkyl, 2-4C alkenyl or opt. substd. benzyl, and n is 1, 2 or 3. - Cpds. are made by reaction of an amine of formula (II) with a cpd. of formula XCOZ, in which Z is halogen, OH or OR, and R is an active gp.
