Reaction Steps
Using the procedure of Example 2, 257 mg of racemic-3,4-dihydro-7-hydroxy-2-methyl-4-oxo-8-n-propyl-2H-1-benzopyran-2-propanoic acid ethyl ester was reduced with borane.tetrahydrofuran and boron trifluoride etherate. There was obtained 195 mg of racemic-3,4-dihydro-7-hydroxy-2-methyl-8-n-propyl-2H-1-benzopyran-2-propanoic acid ethyl ester as a pale yellow oil, after chromatographic purification on silica gel.
