Abstract

A procedure for the preparation of benzopyran-5-ol of formula: ** (See formula) ** or a pharmaceutically acceptable acid addition salt thereof, where R4 is an alkyl group of 1-24 carbon atoms, and R5 is hydrogen, alkyl, alkenyl, alkynyl, aralkyl or acyl, whose process is characterized in that it consists of carrying out the reaction of CH3Mg Y where Y is chlorine, bromine or ** (See formula) ** or a salt thereof in which R6 is an optionally substituted phenyl group and then if desired to react the resulting compound where R5 is hydrogen with R5Cl, R5Br or R5I.
