Sodium borohydride → HCID 86586760, compound

Participants

Reaction Steps

Sodium borohydride (13 mg, 0.34 mmol) was added to a solution of (1R*,2R*,5S*,6R*)-8-benzyl-2-{[3,5-bis(trifluoromethyl)phenyl]methoxy}-6-[2-(2-oxopropyl)-2H-tetrazol-5-yl]-1-phenyl-8-azabicyclo[3.2.1]octane (Compound 3i in Table 3; 0.2 g, 0.31 mmol) in methanol (10 ml) and THF (2 ml). The mixture was stirred at room temperature for 18 hours. The reaction mixture was concentrated in vacuo and the residue partitioned between saturated sodium hydrogen carbonate and ethyl acetate. The organic layer was separated, dried (MgSO4), filtered and concentrated. The residue was chromatographed on silica gel eluting with 25 and 35% ethyl acetate/iso-hexanes to yield the title compound (189 mg, 95%).
