Procedure
To a stirred and cooled (5° C.) solution of 20 parts of intermediate 2, namely phenyl (6-quinoxalinyl)methanone in 160 parts of methanol were added portionwise 3.2 parts of sodium tetrahydroborate. Upon completion, the reaction mixture was poured into water and the product was extracted with dichloromethane. The extract was washed with water, dried, filtered and evaporated to dry, yielding 20 parts (100%) of α-phenyl-6-quinoxalinemethanol as an oily residue (interm. 3).
