2-Chloro-4-(2-methoxyethoxy)pyrimidine (91 mg, 0.485 mmol) and 3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (113 mg, 0.485 mmol) were dissolved in Dioxane (4 ml), and methanesulfonic acid (0.033 ml, 0.509 mmol) was added. The mixture was heated to 100° C. for 18 h. The mixture was allowed to cool to room temperature, quenched with saturated aqueous sodium bicarbonate and extracted with EtOAc (2×). The combined organics were dried over Na2SO4, filtered and concentrated in vacuo to obtained 4-(2-methoxyethoxy)-N-[3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]pyrimidin-2-amine (160 mg, 86%) as a brown solid. MS APCI: [M+H]+ m/z 386. 1H NMR (500 MHz, CDCl3) δ 8.08 (d, J=5.8, 1H), 7.93 (s, 1H), 7.48 (s, 1H), 7.34 (s, 1H), 6.26 (d, J=6.0, 1H), 4.58 (m, 2H), 3.77 (m, 2H), 3.42 (s 3H), 2.37 (s, 3H), 1.34 (s, 12H).
