Procedure

A mixture of tert-butyl N-[3-chloro-4-(4-chlorothiazolo[5,4-c]pyridin-2-yl)-5-fluoro-phenyl]carbamate (56 mg, 0.135 mmol), 6-methylpyrimidin-4-amine (44 mg, 0.40 mmol), Pd2(dba)3 (6.2 mg, 0.00676 mmol), XantPhos (7.8 mg, 0.0135 mmol) and Cs2CO3 (88 mg, 0.27 mmol) in 1,4-Dioxane (2 mL) was heated at 150° C. in a microwave reactor for 20 min, The mixture was filtered through Celite, washed with EtOAc, concentrated. The crude product was purified by reverse phase HPLC to give the title compound (5.4 mg, 10% yield) as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ 10.48 (s, 1H), 8.61 (s, 1H), 8.39 (d, J=5.6 Hz, 1H), 7.75 (d, J=5.6 Hz, 1H), 7.58 (s, 1H), 6.66 (s, 1H), 6.49 (dd, J=12.7, 2.0 Hz, 1H), 6.34 (s, 2H), 2.38 (s, 3H). LCMS (Method B): RT=3.43 min, m/z 387.0 [M+H+].
