Procedure

2-(2-Amino-phenyl)-imidazo[2,1-b]thiazole-6-carboxylic acid methyl ester (27 mg, 0.095 mmol) was mixed with 1 mL of pyridine along with 22 mg of 3,4,5-trimethoxybenzoyl chloride. The reaction mixture was reacted in a microwave reactor at 160° C. for 10 minutes. It was then cooled to room temperature and concentrated. The resulting crude product was purified by preparative HPLC using a mixture of aqueous acetonitrile that has been buffered with 0.1% TFA to afford 108 mg of 2-[2-(3,4,5-trimethoxybenzoylamino)-phenyl]-imidazo[2,1-b]thiazole-6-carboxylic acid methyl ester (MS, M++H=468).
