To a solution of 2-(2-chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl)propan-2-ol (63 mg, 0.20 mmol) in acetonitrile (3.6 ml) in a microwave reaction vessel was added 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)isoquinolin-1-amine (110 mg, 0.40 mmol), Bis(triphenylphosphine)palladium(II) chloride (7.02 mg, 0.010 mmol) and 1M sodium carbonate in water (0.60 ml). The reaction vessel was sealed and heated in the microwave at 140° C. for 20 minutes. LC-MS of the reaction mixture showed no more starting material. The solvent was evaporated and the resulting oil was purified on silica gel (0 to 20% of 2N NH3 in MeOH/DCM). The resulting oil was further purified by reversed phase HPLC to give 141 as an off-white solid (4.7 mg, 6%) 1H NMR (DMSO d6, 400 MHz) 9.02 (d, 1H, J=8.4 Hz), 8.26 (s, 1H), 8.26 (d, 1H, J=8.4 Hz), 7.67 (t, 1H, J=7.6 Hz), 7.50 (t, 1H, J=7.6)m 7.33 (s, 1H), 7.11 (s, 2H), 5.84 (s, 1H), 3.98-3.94 (m, 4H), 3.81-3.78 (m, 4H), 1.61 (m, 6H). LCMS m/z: 422 (MH+)
