Reaction Steps
Solid sodium triacetoxyborohydride (107 mg, 0.504 mmol) was added to a stirred mixture of 2-[1-{(2R,3R,4R)-2-[(1R)-1-(3,5-bis(trifluoromethyl)phenyl)ethoxy]-3-(4-fluorophenyl)-tetrahydropyran-4-carbaldehyde (Description 11; 121 mg, 0.36 mmol), (1S,4R)-4,7,7-trimethyl-3-oxo-2-oxa-bicyclo[2.2.1]heptane-1-carboxylic acid (4R)-2-oxa-8-aza-spiro[4.5]dec-4-yl ester trifluoroacetate (Description 10; 130 mg), triethylamine (0.1 ml, 0.72 mmol) and dichloromethane (3 ml) at room temperature. The mixture was stirred for 45 minutes, quenched with saturated aqueous NaHCO3 and extracted into dichloromethane. The organic extract was dried (Na2SO4) and concentrated. The residue was purified by preparative TLC (dichloromethane:methanol) to give the title compound (100 mg). The HCl salt was prepared and recrystallised from ethyl acetate:methanol.
