Procedure

A solution of 3,4-epoxy-3,4-dihydro-2,2,6-trimethyl-2H-1-benzopyran (7 g, see J. Med. Chem. 26, 1582, 1983) in concentrated ammonia solution (90 ml) and ethanol (160 ml) was stirred at room temperature for 5 days. Evaporation of solvent gave the title compound (7 g) as a crude solid which was used directly, without purification.
