Participants

Reaction Steps

Sodium triacetoxyborohydride (4.77 g, 22.5 mmol) was added to a solution of 8-phenyl-1,4-dioxaspiro[4.5]decane-8-carboxaldehyde (J. Med. Chem. 1975, 18, 593-599). (1.1 g, 4.5 mmol) and 3,5-bis(trifluoromethyl)benzenemethanamine (1.1 g, 4.5 mmol) in dichloroethane (50 mL) and the mixture was stirred at room temperature overnight. The mixture was poured into saturated aqueous sodium hydrogen carbonate (50 mL) and extracted with ethyl acetate (2×50 mL). The combined organic fractions were washed with brine (50 mL), dried (MgSO4) and the solvent was evaporated under reduced pressure. The residue was purified by flash column chromatography on silica gel, eluting with isohexane/EtOAc (75:25), to give the title compound as a yellow oil (1.0 g, 47%). m/z (ES+) 473 (M+1).
