Lithium aluminium hydride (0.712 mL, 0.71 mmol) was added dropwise to tert-butyl 1-(4-chlorophenyl)-2-cyanoethylcarbamate (Intermediate 24) (200 mg, 0.71 mmol) in THF (4 mL) at 20° C. under nitrogen. The resulting solution was stirred at 20° C. for 2 hours. The reaction mixture was quenched with NaOH (1M) (1 mL) and the solution was filtered. The solution was diluted with EtOAc (20 mL), and washed with water 2× (10 mL). The organic layer was dried over MgSO4, filtered and evaporated to afford tert-butyl 3-amino-1-(4-chlorophenyl)propylcarbamate (203 mg, 100%) as a gum. m/z (ESI+) (M+H)+=285; HPLC tR=2.33 min.
