Reaction Steps

2-[1-[[5-Methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl]-4-piperidinyl]-4-thiazolecarbonyl chloride (210 mg, 0.5 mmol) (i.e. the product of Example 19, Step D) was treated with a solution of (1R)-2,3-dihydro-N,2-dimethyl-1H-inden-1-amine (147 μL, 1.0 mmol) and triethylamine (139 μL, 1.0 mmol) in 5 mL of dichloromethane. The reaction mixture was stirred at room temperature for 2 h, passed through a Varian 1005 Chem Elut™ column pretreated with 3 mL of 1 N aqueous hydrochloric acid. The column was flushed with three column volumes of dichloromethane. The collected dichloromethane solution was evaporated in vacuo and purified by medium-pressure liquid chromatography on silica gel using 50-100% of ethyl acetate in 1-chlorobutane as eluant to give 214 mg of the title compound, the product of present invention as a white foam.
