To a mixture of 6-chloro-N-(5-methyl-4-phenyl-thiazol-2-yl)-nicotinamide (50 mg, 0.152 mmol) and anhydrous N-methylpyrrolidinone (10 mL) in a sealed tube was added 4-(3-trifluoromethyl-phenyl)-piperidine hydrochloride (80 mg, 0.30 mmol) followed by diisopropylethylamine (0.11 mL, 0.63 mmol). The mixture was heated in an oil bath at 70° C. overnight. After concentration, the crude was purified by RP-HPLC to give 4-(3-trifluoromethyl-phenyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-5′-carboxylic acid (5-methyl-4-phenyl-thiazol-2-yl)-amide as an off-white powder. LCMS calcd for C28H25F3N4OS (m/e) 522, obsd 523 (M+H).
