A mixture of 5-chloro-7-morpholin-4-yl-2-(3-morpholin-4-ylazetidin-1-ylmethyl)thiazolo[5,4-d]pyrimidine (100 mg, 0.24 mmol), 2-methyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)benzofuran (94 mg, 0.37 mmol), tetrakis(triphenylphosphine)palladium (28 mg, 0.02 mmol) and Cs2CO3 (159 mg, 0.48 mmol) in dioxane (6 mL) and H2O (3 mL) was purged with argon then heated at 140° C. for 30 min in a microwave reactor. The reaction mixture was loaded onto an Isolute® SCX-2 cartridge which was washed with DCM/MeOH and the product eluted with 2M NH3/MeOH. The resulting residue was purified by column chromatography (Si—PCC, MeOH:EtOAc, 0-5%) to afford 212 as a cream solid (58 mg, 48%). LCMS (Method G): RT 9.83 min, [M+H]+ 507.3. 1H NMR (CDCl3, 400 MHz): δ 8.39-8.36 (m, 1 H); 7.45-7.42 (m, 1 H); 7.32-7.24 (m, 2 H); 4.40 (m, 4 H); 4.01 (s, 2 H); 3.89 (m, 4 H); 3.70 (m, 6 H); 3.18-3.08 (m, 3 H); 2.92 (s, 3H) and 2.36 (m, 4 H)
