実験手順

A solution of (4-benzyl-6-methyl-pyrimidin-2-yl)-piperidin-4-yl-amine hydrochloride (159 mg, 0.5 mmol), 3,5-dichloro-[1,2,4]thiadiazol (39 mg, 0.25 mmol) and N,N-diisopropylethylamine (85 L, 0.5 mmol) in tetrahydrofurane (2 mL) was heated to 95° C. 4 hours under nitrogen. The reaction was diluted with water and extracted twice with ethyl acetate. The combined organic layers were washed with saturated aqueous NaCl solution, dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel using Et2O as eluent. The title compound was obtained as a colorless oil (52 mg, 52%).
