Reaction Steps

To a stirred solution of 30 parts of intermediate 45, namely 2-methyl-1-[4-(methylamino)-3-nitrophenyl]-1-propanone in 320 parts of methanol were added dropwise 15 parts of sodium tetrahydroborate (the temperature was kept at 20° C.). Upon complete addition, stirring was continued for 30 minutes at room temperature. The reaction mixture was poured into water and the product was extracted with trichloromethane. The extract was dried, filtered and evaporated to dry, yielding 30 parts (100%) of 4-(methylamino)-α-(1-methylethyl)-3-nitrobenzenemethanol as an oily residue (interm. 46).
