Procedure

A mixture of (1-{4-[2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purin-8-ylmethyl]piperazine-1-carbonyl}cyclopropyl)carbamic acid tert-butyl ester (0.123 g, 0.19 mmol) in DCM/TFA (5 mL/5 mL) was stirred for 4 h at room temperature. The reaction mixture was loaded onto an Isolute® SCX-2 cartridge. The cartridge was washed with MeOH and the desired product was eluted using 2 M NH3 in MeOH. The eluent was concentrated in vacuo and the residue was purified by flash chromatography (Si—PPC, MeOH:DCM, gradient 0:100 to 10:90) to give 432 as a white solid (0.066 g, 64%). LCMS (Method I): RT=2.47 min, [M+H]+ 462.3. 1H NMR (400 MHz, DMSO-d6): δ 8.04-8.00 (m, 1 H); 7.66-7.61 (m, 1 H); 7.28-7.21 (m, 2 H); 4.18-4.22 (m, 4 H); 3.85 (s, 3 H); 3.82 (s, 2 H); 3.78 (t, J=4.6 Hz, 4 H); 3.58-3.53 (m, 4 H); 3.27 (q, J=7.4 Hz, 2 H); 2.55-2.45 (m, 4 H); 1.34 (t, J=7.4 Hz, 3 H); 0.92-0.87 (m, 2 H); 0.82-0.75 (m, 2 H)
