Procedure

A mixture of [1-(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-piperidin-4-yl]dimethylamine (50 mg, 0.13 mmol), benzimidazole (32 mg, 0.27 mmol) and concentrated HCl (53 μL, 0.64 mmol) in 1,4-dioxane (1 mL) was subjected to microwave irradiation at 150° C. for 40 min. The reaction mixture was cooled to ambient temperature and loaded onto an Isolute® SCX-2 cartridge (2 g). The cartridge was then washed with MeOH and the desired product was subsequently eluted using 2 M NH3 in MeOH. The eluent was collected and concentrated in vacuo. The resultant residue was purified by flash chromatography (Si—PPC, DCM:2 M NH3 in MeOH 100:0 to 98:2 to 95:5 to 90:10) to afford 110 as a white solid (38 mg, 63%). LCMS (Method F): RT=5.12 min, [M+H]+ 478.2. 1H NMR (CDCl3, 400 MHz): δ 9.04 (s, 1 H); 8.61-8.57 (m, 1 H); 7.86-7.82 (m, 1 H); 7.43-7.31 (m, 2 H); 7.27 (s, 1H); 4.07 (t, J=4.8 Hz, 4 H); 3.92 (t, J=4.8 Hz, 4 H); 3.82 (s, 2 H); 3.08-2.99 (m, 2 H); 2.30 (s, 6 H); 2.20-2.10 (m, 3 H); 1.88-1.78 (m, 2 H); 1.66-1.54 (m, 2 H)
