Procedure

To a solution of (1S,4R)-1,2,3,4-tetrahydro-4-(methylamino)-1-naphthalenol and its enantiomer (283 mg, 1.6 mmol) (i.e. the product of Example 26, Step A) and triethylamine (0.5 mL, 3.6 mmol) in 5 mL of dichloromethane was gradually added 2-[1-[[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl]-4-piperidinyl]-4-thiazolecarbonyl chloride (605 mg, 1.44 mmol) (i.e. the product of Example 19, Step D) at 0° C. The reaction mixture was stirred at room temperature for 1 h, diluted with 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 700 mg of the title compounds, compounds of the present invention as an off-white powder.
