Triethylamine → N-methyl-2-[1-[[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl]-4-piperidinyl]-N-(1,2,3,4-tetrahydro-2-methyl-1-naphthalenyl)-4-thiazolecarboxamide

Participants

Reaction Steps

To a solution of 1,2,3,4-tetrahydro-N,2-dimethyl-1-naphthalenamine (115 mg, 0.66 mmol) and triethylamine (0.12 mL, 0.825 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 (231 mg, 0.55 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 to give 270 mg of the title compound, the product of present invention as a white foam.
