Reaction Steps

To a solution of 3-(3-aminophenyl)-1-perhydro-2H-pyran-2-yl-1H-indazole-5-carbonitrile (0.150 g, 0.47 mmol) in tetrahydrofuran (5 mL), was added nicotinoyl chloride hydrochloride (0.167 mg, 0.94 mmol) and triethyl amine (0.327 mL, 2.35 mmol). After stirring at room temperature overnight, the crude mixture was partitioned between ethyl acetate and water. The crude compound was isolated as a gummy solid. The yield was not calculated: ES-MS (m/z) 424 [M+H]+.
