Reaction Steps
2-(6-Chloro-3,4-dihydro-1(2H)-benzopyran-4-yl)ethanol may be prepared by proceeding as in Example 1, but starting with lithium aluminium hydride (1.97 g), and ethyl (6-chloro-3,4-dihydro-1(2H)-benzopyran-4-yl)ethanoate (6.6 g) in tetrahydrofuran (120 cc). 2-(6-methoxy-3,4-dihydro-1(2H)-benzopyran-4-yl)ethanol (5.5 g) is thus obtained in the form of a colourless oil.
