The tert-butyl{2-[(3-{5-[2-({(3R)-1-[(4-chlorophenyl)sulfonyl]piperidin-3-yl}amino)-pyrimidin-4-yl]imidazo[2,1-b][1,3]thiazol-6-yl}phenyl)amino]-2-oxoethyl}carbamate (71 mg, 0.098 mmol) was dissolved in dioxane (3 ml) and treated with a 4N HCl solution in dioxane (1 ml). The mixture was stirred at room temperature for 3 hours. The volatiles were removed in vacuo and the residue was triturated in ether. Filtration afforded the title compound as a yellow solid (65 mg). M.p.=208-212° C. 400 MHz 1H NMR (DMSO-d6) δ: 10.69 (s, 1H), 8.18 (br. s, 3H), 8.13 (d, J=5.9 Hz, 1H), 7.88 (t, J=1.6 Hz, 1H), 7.79-7.75 (m, 2H), 7.71-7.66 (m, 3H), 7.48-7.43 (m, 2H), 7.34 (d, J=7.8 Hz, 1H), 6.45 (d, J=5.9 Hz, 1H), 5.15 (br. s, 3H), 4.04-3.95 (m, 1H), 3.79 (d, J=5.5 Hz, 2H), 3.70 (dd, J=11.3, 4.3 Hz, 1H), 3.48-3.41 (m, 1H), 2.57-2.48 (m, 1H), 2.42 (t, J=10.6 Hz, 1H), 1.95-1.82 (m, 2H), 1.67-1.54 (m, 1H), 1.48-1.37 (m, 1H). LCMS: 623 [M+H]. Calc. for C28H27N8O3S2Cl.2.52HCl: C, 47.03; H, 4.16; N, 15.67. Found C, 47.04; H, 3.97; N, 15.46.
