Reaction Steps

A suspension of 1,1-dimethylethyl 4-(5-(2-chloro-4-pyrimidinyl)-4-{2-fluoro-3-[(3-furanylsulfonyl)amino]phenyl}-1,3-thiazol-2-yl)-1-piperidinecarboxylate (53 mg, 0.085 mmol) in ammonium hydroxide solution (28%, 2 mL, 51.4 mmol) sealed in a 5-mL microwave tube was heated at 90° C. for 3 h under the microwave conditions. The mixture was concentrated and dried under high vacuum to give 49 mg of the title compound. MS (ESI): 501.1 [M+1]+.
