実験手順
A solution of {4-[4-(2-oxo-1,2-dihydro-quinolin-3-yl)-thiazol-2-yl]-phenyl}-carbamic acid tert-butyl ester (Example 97, 70 mg, 0.17 mmol) in 0.8 mL of CH2Cl2 and 0.8 mL of TFA was stirred at RT for 1 h. Solvents were removed under vacuum and the residue was azeotroped twice with toluene. To the flask, 4.0 mL of aqueous HCl (1 M) was added and solids formed. The solvent was removed again and the solid was azeotroped with toluene twice. The solid was dried under vacuum overnight to afford the title compound as a light yellow solid. MS m/z: 320.2 (M+1). Anal. Calc'd for C18H13N3OS.0.8H2O.1.6HBr: C, 55.13; H, 4.16; N, 10.72; O, 7.34; S, 8.18. Found: C, 55.24; H, 4.15; N, 10.66; O, 7.45; S, 8.21.
