Procedure

A mixture of 2-[4-[5-(3,5-dichlorophenyl)-4,5-dihydro-5-(trifluoromethyl)-3-isoxazolyl]-1-naphthalenyl]-5(4H)-oxazolone (i.e. the title product of Step A) (50 mg) and (aminomethyl)cyclopropane (0.1 mL) in N,N-dimethylformamide (1 mL) was irradiated with microwave radiation to maintain a temperature around 150° C. for 30 minutes. The reaction mixture was diluted with water and extracted with ethyl acetate. The organic layer was washed with brine, dried with anhydrous sodium sulfate, and concentrated. The residue was purified by column chromatography on silica gel using hexanes/ethyl acetate (3:2 to 3:7) as eluent to afford the title compound, a compound of the present invention, as a pale yellow solid (47 mg, 82% yield).
