Abstract
Process for the preparation of new coumarin derivatives of the general formula ** (See formula) ** in which R1 means an alkyl, phenyl or phenylalkyl radical which may be substituted in the phenyl nucleus by halogen atoms, R2 and R3 signify, hydrogen, a halogen atom or an alkyl or lower alkoxy group, R4 means hydrogen or a radical corresponding to the given definition for R1, or a lower dialkylaminoalkylene group with 2 to 4 atoms of carbon in the alkylene group, and R5 means hydrogen or a lower alkyl group which can be directly linked to an alkyl group R4, characterized by reacting compounds of the general formula II ** (See formula) ** with compounds of the general formula ** (See formula) ** in whose formulas Hal means chlorine or bromine and R1, R2, R3, R4 and R5 have the meaning expressed above, and, if desired, a basic radical R4 of a compound thus obtained, of the general formula I, is salified with an inorganic or organic acid.
