Cyanuric chloride → HCID 9945734, compound

Participants

Reaction Steps

Cyanuric chloride (24 mg) was added to a suspension of 4-difluoromethoxy-2-ethylbenzooxazole-7-carboxylic acid (0.1 g) in dichloromethane (20 ml) at room temperature under an atmosphere of nitrogen. Triethylamine (0.07 ml) was added dropwise, followed by 3-methylisoxazol-4-ylamine (46 mg) in dichloromethane (5 ml). The reaction was left to stir for 2 hours before evaporation of the solvent in vacuo. Purification by column chromatography on silica eluting with 50% ethyl acetate in heptane afforded, after trituration with diethyl ether-hexane, the title compound as a white solid (5 mg).
