Reaction Steps

To a stirred solution of diborane:dimethyl sulfide complex (2M) in THF (30 mL) was added drop wise a solution of dry THF (25 mL) and 1-(3-chlorophenyl)-4-(3-phenylpropionyl)piperazine (1.28 g, 3.86 mmol). The reaction mixture was stirred at room temperature for 18 h, quenched by the addition of MeOH-HCl (25 mL), and the solvents removed under reduced pressure. Additional MeOH was added and removed under reduced pressure to give a tan solid. This was dried for 18 h under vacuum then recrystallized from MEK to give 0.9 g (67%) of colorless crystals, mp 168-169° C.
