TFA (1 mL) was added to a solution of tert-butyl 4-((4-(2-(2-amino-2-oxoethyl)phenethyl)-5-methylpyrimidin-2-yl)amino)benzylcarbamate (A114) (0.043 g, 0.090 mmol) in DCM (3 mL) and the resulting solution stirred at room temperature for 4 hours. The volatiles were removed in vacuo then 2 M aqueous K2CO3 (5 mL) and water (15 mL) were added to the residue. The resulting suspension was sonicated for 1 minute, filtered and the filter cake dried to give the title compound 27 as a light tan solid (0.028 g, 82%); 1H NMR (300 MHz, d6-DMSO) δ 9.30 (s, 1H), 8.16 (s, 1H), 7.70 (d, J=8.5 Hz, 2H), 7.43 (s, 1H), 7.12-7.27 (m, 6H), 6.93 (s, 1H), 3.64 (s, 2H), 3.49 (s, 2H), 3.34 (brs, 2H), 3.02-3.07 (m, 2H), 2.85-2.90 (m, 2H), 2.06 (s, 3H). LCMS-B: rt 4.666 min; m/z 376 [M+H]+.
