Reaction Steps

A mixture of 1-[1-[[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl]-4-piperidinyl]-1H-pyrazole-3-carboxylic acid (270 mg, 0.7 mmol) (i.e. the product of Example 18, Step E), N-(3-dimethylaminopropyl)-Y-ethylcarbodiimide hydrochloride (EDC) (147.61 mg, 0.77 mmol) and N-methylmorpholine (0.088 mL, 0.8 mmol) in 5 mL of dichloromethane was stirred at room temperature for 15 minutes. (1R)-1,2,3,4-tetrahydro-N-methyl-1-naphthalenamine (124.16 mg, 0.77 mmol) (i.e. the product of Example 6, Step A) was added and the reaction mixture was stirred at room temperature for 16 h. The reaction mixture was poured in water, and the organic layer was subsequently washed with water, 1 M aqueous hydrochloric acid, water, saturated aqueous solution of sodium bicarbonate, brine. The filtered reaction mixture was dried over magnesium sulfate and evaporated in vacuo. The crude product was purified by medium-pressure liquid chromatography on silica gel using 75-100 of ethyl acetate in hexanes as eluant to give 55 mg of the title compound, a compound of the present invention as an oil.
