Abstract

1,226,896. Coumarin derivatives. LES LABORATOIRES DAUSSE. 12 June, 1969 [14 June, 1968; 15 July, 1968; 13 Sept., 1968], No. 29954/69. Heading C2C. [Also in Division A5] Compounds of the general formula (R<SP>1À2</SP>=H or C 1-6 alkyl or -NR<SP>1</SP>R<SP>2</SP>=heterocyclic radical which may contain a second heteroatom and/or be substituted by one or more Me, Et radicals) and their acid addition salts are prepared by heating a 4-halomethyl-7- hydroxycoumarin with NHR<SP>1</SP>R<SP>2</SP>, optionally followed by salt formation. The coumarin starting materials are prepared by condensing resorcinol with an ethyl haloacetoacetate.
