Procedure
To a microwave vial containing a stir-bar was added 3-(5-aminopyrazin-2-yl)-6-cyclobutyl-2-fluorophenol (100 mg, 0.386 mmol), 5-bromo-2-chloropyrimidine (74 mg, 0.39 mmol), cesium carbonate (188 mg, 0.580), and DMSO (2 mL). The vial was sealed and heated in the microwave for 30 minutes at 120° Celsius. The mixture was cooled to rt then passed through a syringe filter and the filtrate subjected to HPLC purification to give the title compound. 1H NMR (500 MHz, 2 mL) δ 8.69 (d, J=1.5, 2H), 8.24 (s, 1H), 8.10 (s, 1H), 7.79-7.69 (m, 1H), 7.27 (d, J=8.3, 1H), 3.72-3.58 (m, 1H), 2.23-2.10 (m, 3H), 2.02-1.94 (m, 1H), 1.89-1.75 (m, 1H).
