実験手順

A solution of 2-(5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(5-fluoro-6-methoxypyridin-3-ylamino)pyridin-3-yl)-2-morpholinopropanenitrile (0.500 g, 0.708 mmol) in THF (2 mL) at 0° C. was treated with methylmagnesium bromide (3.0 M in diethyl ether; 1.181 mL, 3.54 mmol). The cooling bath was removed after 10 min, and the reaction was allowed to warm to ambient temperature. After 2 h total, the reaction was cooled to 0° C. and quenched with EtOAc (1 mL) followed by ice and sat'd aq. NH4Cl. The reaction was partitioned between satd NH4Cl and DCM. The aqueous layer was extracted with DCM (3×) and the combined organic extracts were dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. The material was treated with DCM and purified by silica gel chromatography using 10-80% EtOAc/hexane. The product-containing fractions were concentrated to give 4-(2-(5-fluoro-6-methoxypyridin-3-ylamino)-5-(2-morpholinopropan-2-yl)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (0.363 g, 0.522 mmol, 73.7% yield) as a yellow solid. m/z (ESI, +ve ion) 695 (M+H)+. 1H NMR (400 MHz, CDCl3) δ 11.86 (s, 1H); 8.96 (d, J=2.5 Hz, 1H); 8.47 (d, J=2.5 Hz, 1H); 8.13 (dd, J=12.5, 2.2 Hz, 1H); 7.91-8.01 (m, 1H); 7.17-7.26 (m, 4H); 6.75-6.96 (m, 4H); 4.89 (s, 2H); 4.84 (s, 2H); 4.02 (s, 3H); 3.82 (s, 3H); 3.79 (s, 3H); 3.55-3.65 (m, 4H); 2.59 (s, 3H); 2.42-2.51 (m, 4H); 1.35 (s, 6H).
