To a solution of 1-(3-(2-(1-(4-fluorophenyl)cyclohexyl)ethyl)-4,5-dihydronaphtho[1,2-c]isoxazol-7-yl)ethane-1,2-diol (Preparation 26B, 0.097 g, 0.223 mmol) in methanol (2 mL) at 0° C. was added a solution of sodium periodate (0.057 g, 0.268 mmol) in water (2 mL) dropwise. The white heterogeneous reaction mixture was stirred for 40 mins. at 0° C. and partitioned between ethyl acetate and water. The ethyl acetate layer was washed with brine, dried over sodium sulfate, concentrated, dried in vacuo to yield 3-(2-(1-(4-fluorophenyl)cyclohexyl)ethyl)-4,5-dihydronaphtho[1,2-c]isoxazole-7-carbaldehyde. LC/MS M+1=402.23.
