A mixture of 2-chloro-4-morpholin-4-yl-6-(3-morpholin-4-ylazetidin-1-ylmethyl)thieno[3,2-d]pyrimidine (100 mg, 0.24 mmol), 2-methyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)benzofuran (94 mg, 0.36 mmol), tetrakis(triphenylphosphine)palladium (28 mg, 0.02 mmol) and Cs2CO3 (160 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, washed with DCM/MeOH then eluted with 2M NH3/MeOH. The resulting residue was purified by column chromatography (Si—PCC, MeOH:DCM, 0-5%) to afford 213 as a white foam (98 mg, 81%). LCMS (Method G): RT 9.09 min, [M+H]− 506.3. 1H NMR (CDCl3, 400 MHz): δ 8.42-8.39 (m, 1 H); 7.46-7.42 (m, 1 H); 7.32-7.24 (m, 3 H); 4.02 (t, J=4.7 Hz, 4H); 3.97 (s, 2 H); 3.89 (t, J=4.7 Hz, 4 H); 3.73 (m, 4 H); 3.63 (s, 2 H); 3.06 (m, 3 H); 2.93 (s, 3 H) and 2.33 (m, 4 H)
