Procedure

To 1.8 ml of a 1 M solution of isopropyl magnesium bromide in tetrahydrofuran (1.8 mmol) a solution of 500 mg (0.865 mmol) N-(3,5-bis-trifluoromethyl-benzyl)-6-iodo-N-methyl-4-o-tolyl-nicotinamide (Example 4) in 10 ml tetrahydrofuran was added dropwise at 40° C. After 2 h 0.116 ml (I1.15 mmol) benzaldehyde were added. The reaction mixture was allowed to warm to room temperature over night. Addition of water and saturated aqueous ammonium chloride solution was followed by extraction with three portions of ethyl acetate. The combined organic extracts were dried with sodium sulfate and concentrated. Column chromatography afforded 274 mg (57%) of the title compound as an off-white foam.
