Procedure

To a solution of 1,2,3,4-tetrahydro-N-methyl-1-naphthalenamine (145 mg, 0.9 mmol) (prepared by the method described from Example 6, Step A) and triethylamine (0.16 mL, 1.13 mmol) in 2 mL of dichloromethane was gradually added 2-[1-[[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl]-4-piperidinyl]-4-thiazolecarbonyl chloride (316 mg, 0.75 mmol) (i.e. the product of Example 19, Step D) at 0° C. The reaction mixture was stirred at room temperature for 16 h, diluted with 4 mL of dichloromethane, and washed with water, 1 N aqueous hydrochloric acid, water, saturated solution of sodium bicarbonate and brine. The filtered reaction mixture was dried over magnesium sulfate and concentrated in vacuo. The crude product was purified by medium-pressure liquid chromatography on silica gel using 60-100% of ethyl acetate in hexanes as eluant to give 242 mg of the title compound, a compound of the present invention as white foam.
