反応手順

The mixture of 4-(pentylamino)-1H-imidazole-5-carbonitrile (200 mg, 1.12 mmol), benzohydrazide (229 mg, 1.68 mmol) and potassium carbonate (100 mg, 0.72 mmol) in 1-butanol (6 ml) in a sealed tube was stirred at 170° C. for 14 hours. The reaction was diluted with water and extracted with EtOAc three times. The combined organic layers was dried with sodium sulfate, filtered, and concentrated in vacuo. The crude residue was purified by preparative LCMS (method A) to yield the desired product (50 mg, 17% yield). LCMS calculated for C16H21N6 (M+H): 297.2. found 297.1.
