Reaction Steps

A suspension of 1,1-dimethylethyl 4-[5-(2-chloro-4-pyrimidinyl)-4-(3-{[(2,6-difluorophenyl)sulfonyl]amino}-2-fluorophenyl)-1,3-thiazol-2-yl]-4-methyl-1-piperidinecarboxylate (39 mg, 0.057 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 obtain the title compound (40 mg). MS (ESI): 661.4 [M+1]+.
