Reaction Steps

To a solution of 4-[1-(3,5-bis-trifluoromethyl-benzyl)-5-phenyl-1H-[1,2,3]triazole-4-carbonyl]-5-(2-chloro-phenyl)-isoxazole-3-carbaldehyde (75 mg, 0.12 mmol) in THF (0.6 mL) at −78° C. under N2, add methylmagnesium bromide (120 μL, 3.0 M in Et2O). Allow the reaction to warm to 0° C. and stir for two h., then quench the reaction with a saturated solution of NH4Cl (1 mL). Dilute the mixture with CH2Cl2 (1 mL), wash with H2O (1 mL) and brine (1 mL). Pass the organic layer through a Varian ChemElute® drying cartridge and concentrate. Purify the residue by chromatography on silica gel using a gradient of 10:1 Hex/EtOAc to 2:1 Hex/EtOAc to afford the title compound (4.3 mg, 6%). MS/ES (M+1)=620.9.
