Abstract
PURPOSE: To prepare an isoquinoline alcohol derivative useful as an antiphlogistic, analgesic, antithrombogenetic agent, easily and in high yield, by hydrolyzing a specific ester, e.g. 3-isoquinolylethyl acetate, etc.
CONSTITUTION: The compound II [R1 is monofunctional substitution group; n is 0W2; when n is 0, (R1)n is H, and when n is 2, two R1s may together form a ring; R2 is H, lower alkyl; R3 is lower alkyl] is prepared by the hydrolysis of an ester I, e.g. 3-isoquinolylethyl acetate, 3-isoquinolylethyl propionate, etc., in a solvent such as water, methanol, etc., in the presence of a mineral acid such as HCl, or an alkali such NaOH, at 0W120°C.
