Procedure

To a solution of (1R,4R)-1,2,3,4-tetrahydro-4-(methylamino)-1-naphthalenol and its enantiomer (70 mg, 0.39 mmol) (i.e. the product of Example 28, Step A) and triethylamine (0.082 mL, 0.59 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 (181 mg, 0.43 mmol) (i.e. the product of Example 19, Step D) at 0° C. The reaction mixture was stirred at room temperature for 3 h, diluted with 5 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 0-20% of acetone in ethyl acetate as eluant to give 160 mg of the title compounds, compounds of the present invention as a white foam.
