Reaction Steps

A mixture of 1-(6-(6-amino-2-methylpyrimidin-4-yl)-5-(5-fluoro-6-methoxypyridin-3-ylamino)pyrazin-2-yl)ethanone (11 mg, 0.030 mmol) and methylmagnesium bromide, 3.0 M solution in diethyl ether (10.65 μL, 0.089 mmol, Aldrich, St. Louis, Mo.) in tetrahydrofuran (1 mL) was stirred at 0° C. for 30 min. The reaction mixture was diluted with saturated NH4Cl (5 mL) and extracted with CH2Cl2 (2×10 mL). The organic extracts were washed with saturated NaCl 5 mL) and dried over Na2SO4. The solution was filtered and concentrated in vacuo to give the crude material as a yellow solid. The crude product was purified by silica gel chromatography eluting with 5% MeOH/CH2Cl2 to give 2-(6-(6-amino-2-methylpyrimidin-4-yl)-5-(5-fluoro-6-methoxypyridin-3-ylamino)pyrazin-2-yl)propan-2-ol (8.5 mg, 0.022 mmol, 74.1% yield). 1H NMR (300 MHz, CDCl3) δ 1.63 (s, 6H) 2.66 (s, 3H) 3.66 (s, 1H) 4.03 (s, 3H) 5.01 (s, 2H) 7.45 (s, 1H) 8.11 (d, J=1.90 Hz, 1H) 8.22 (dd, J=12.13, 2.05Hz, 1H) 8.39 (s, 1H) 12.66 (s, 1H). m/z (ESI, +ve ion) 386.1 (M+H)+.
