Sodium borohydride → 3-[(4-Chlorophenyl)methyl]-2-(1-methylethyl)-3,4,5,6,7,8-hexahydrocyclohepta[d]imidazol-4-ol

Participants

Reaction Steps

Sodium borohydride (100 mg) was added to a stirred solution of Intermediate 3 (420 mg) in dichloromethane (3 ml) and methanol (3.00 ml). The reaction mixture was stirred for 1 hour. The reaction mixture was partitioned between EtOAc (50 ml) and water (30 ml). The two phases were separated and the aqueous phase was extracted again with EtOAc (30 ml). The phases were separated, the organic extracts were combined, dried (hydrophobic frit) and concentrated under vacuum to give the title compound (376 mg). LC/MS MH+ 319, Rt 0.77 min (2 minute run).
