Reaktionsschritte
To {2-[6-(2-acetylamino-benzothiazol-4-yloxy)-pyrimidin-4-yl]-5-trifluoromethyl-phenyl}-carbamic acid tert-butyl ester, (Example 150) (0.35 g, 0.60 mmol) was added 4 M HCl in dioxane (25 mL). The mixture was stirred for 16 h and then was concentrated in vacuum. The residue was dissolved in ethyl acetate (40 mL) and washed with saturated NaHCO3 (2×70 mL), dried over Na2SO4 and concentrated in vacuum. Purification by silica gel chromatography (2:1, EtOAc:hexanes) afforded the title compound as thick yellow oil. Mp: 160–161° C. MS (ESI, pos. ion) m/z: 446 (M+1). Anal. Calcd for C20H14F3N5O2S.0.4H2O: C, 53.07; H, 3.30; F, 15.47; N, 12.59. Found: C, 53.12; H, 3.27; F, 15.19; N, 12.70.
