To this solution was added DIPEA (2 equi.) and stirred for 15 minutes followed by addition of 2-aminothiazole (1 equi.) and continued to stir over night at room temperature. Reaction mixture was diluted with dichloromethane, washed with water, brine, dried over anhydrous sodium sulfate, solvent was removed under reduced pressure to get the crude compound which was purified by flash chromatography to get the title product.
