Procedure
A solution of tert-butyl 4-((4-(2-(2-amino-2-oxoethyl)phenethyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)benzyl(2-hydroxyethyl)carbamate (A75) (0.301 g, 0.525 mmol) and trifluoroacetic acid (1.0 mL) in DCM (10 mL) was stirred at room temperature for 22 hours. The volatiles were removed in vacuo and 2 M aqueous sodium hydroxide solution (20 mL) added to the residue. The resulting suspension was sonicated for several minutes then filtered, washing the filter cake with water. Semi preparative HPLC of the filter cake gave the title compound 19 as a white solid (58 mg, 23%); 1H NMR (300 MHz, d4-MeOH) δ 8.61 (s, 1H), 8.53 (s, 1H), 7.83 (d, J=8.5 Hz, 2H), 7.46 (d, J=8.6 Hz, 2H), 7.29-7.19 (m, 4H), 4.19 (s, 2H), 3.82 (t, J=5.2 Hz, 2H), 3.68 (s, 2H), 3.22-3.10 (m, 6H). LCMS-B: rt 5.313 min; m/z 474 [M+H]+.
