Procedure

[2-(Methylsulfonyl)ethyl]amine (267 mg, 2.169 mmol) and N-{3-[5-(2-chloro-4-pyrimidinyl)-2-(1-methylethyl)-1,3-thiazol-4-yl]phenyl}-2-furansulfonamide (100 mg, 0.217 mmol) were combined and heated to 56° C. overnight. The reaction mixture was cooled to rt and diluted with DCM and 10% aqueous HCl. The layers were separated and the water layer was extracted twice more with DCM. The combined organic layers were dried over MgSO4, filtered and concentrated to yield an oil. The oil was chromatographed on silica gel eluting with 100% DCM to 4:6 [DCM:(9:1 EtOAc:MeOH)]. The clean fractions were combined and concentrated to yield an oil. Diethyl ether was added to the oil and concentrated to obtain the title compound as a light brown solid (25.1 mg, 20% yield). 1H NMR (400 MHz, DMSO-d6 heated to 60° C.) δ ppm 10.53-10.65 (m, 1H) 8.06-8.16 (m, 1H) 7.88 (s, 1H) 7.30-7.42 (m, 1H) 7.16-7.30 (m, 4H) 7.05 (d, J=3.6 Hz, 1H) 6.53-6.65 (m, 1H) 6.14-6.27 (m, 1H) 3.59-3.74 (m, 2H) 3.24-3.43 (m, 3H) 2.97 (br. s., 3H) 1.36 (dd, J=6.6, 2.7 Hz, 6H).
