Reaction Steps
A suspension of methyl [(8-methoxy-4-oxo-4H-1-benzopyran-3-yl)oxy]acetate (200 mg) in 6N hydrochloric acid (20 ml) is stirred at 100° C. for 3 hrs. under nitrogen. The reaction is cooled and the product filtered off and sucked dry. Recrystallization from methanol gives white crystals (180 mg. 86%), mp 215°-217° C.
