| description | A process for the preparation of a compound from the group consisting of 7-alkyl- (and 7-cyloalkyl-lower-alkyl-chyl) -4- (4-pyridyl) -2,2,3-trialkyl-5-chromanol and 2, 2-dialkyl-7-alkyl- (and 7-cycloalkyl-lower alkyl) -4- (4-pyridyl) -2H-chromen-5-ol, of formulas **(See formula)** where R1 is lower alkyl and R2 is a member of the group consisting of alkyl and cycloalkyl-lower alkyl, the process of which is to react a compound of formula **(See formula)** where R2 has the meaning given above, with a lower alkyl magnesium halide of formula R1MgX, where R1 has the meaning given above and X is bromine or iodine, at elevated temperature.
