実験手順

A slurry of sodium azide (0.075 g, 1.160 mmol) and N,N-bis(4-methoxybenzyl)-4-(2-(6-methoxypyridin-3-ylamino)-5-(prop-1-en-2-yl)pyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (0.171 g, 0.290 mmol) in CHCl3 (1 mL) at −15° C. was treated with a solution of trifluoroacetic acid (0.223 mL, 2.90 mmol) in CHCl3 (1 mL) added via syringe over 10 min. The cooling reaction mixture was allowed to gradually warm to room temperature and stirred overnight. The reaction was sealed and heated at 60° C. After 2 h, the reaction was poured onto ice and basified with 10 N NaOH. The reaction was partitioned between water and DCM. The aqueous layer was extracted with DCM (3×), and the combined organic layers were dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo to give 4-(5-(2-azidopropan-2-yl)-2-(6-methoxypyridin-3-ylamino)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (0.184 g, 0.291 mmol, 100% yield). m/z (ESI, +ve ion) 633 (M+H)+. 1H NMR (400 MHz, CDCl3) δ 11.67 (br. s., 1H); 8.90 (d, J=2.7 Hz, 1H); 8.38 (d, J=2.5 Hz, 1H); 8.26 (d, J=2.5 Hz, 1H); 7.91 (dd, J=8.8, 2.7 Hz, 1H); 7.18-7.26 (m, 4H); 6.81-6.94 (m, 4H); 6.73 (d, J=8.8 Hz, 1H); 4.90 (s, 2H); 4.81 (s, 2H); 3.94 (s, 3H); 3.82 (s, 3H); 3.78 (s, 3H); 2.59 (s, 3H); 1.64 (s, 6H).
