Reaction Steps

To 4-[Carbamoyl-(2-chloro-phenyl)-methyl]-piperazine-1-carboxylic acid tert-butyl ester 462(0.45 g, 1.27 mmol) in THF (10 mL) at 0° C. was added 1.0M BH3 in THF (5.1 mL). The reaction was allowed to stir at reflux for 18 h. MeOH (5.0 mL) was added to the reaction mixture and mixture was then concentrated to dryness. The resulting residue was taken up in MeOH (10 mL) and allowed to reflux for 1 h. The reaction mixture was concentrated to dryness and the resulting residue was taken up in EtOAc (30 mL) and washed with sat. NaHCO3 (30 mL) and brine (30 mL). The organic phase was concentrated to dryness yielding 0.18 g (43%) product.
