Reaction Steps

1.61 Parts of sodium tetrahydroborate were added dropwise to a stirred solution of 11 parts of (4-amino-3-nitrophenyl) (2-fluorophenyl)methanone in 120 parts of methanol. Upon complete addition, stirring was continued for 1 hour at room temperature. The reaction mixture was poured into water and the product was extracted three times with 75 parts of trichloromethane. The combined extracts were dried, filtered and evaporated, yielding 11.3 parts (100%) of 4-amino-α-(2-fluorophenyl)-3-nitrobenzenemethanol as a residue (interm. 26).
