실험 절차

A mixture of 4-chloro-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (8.82 g, 22.91 mmol), 2-fluoro-5-(morpholinomethyl)pyridin-3-ylboronic acid (5.000 g, 20.83 mmol), potassium acetate (6.28 g, 63.9 mmol), and Am-Phos (1.036 g, 1.666 mmol) in dioxane (40 mL) and water (3.00 mL, 167 mmol) was heated in a CEM Voyager Microwave (Large-Scale Unit) for 25 min at 120° C. while 100 Watts of energy was supplied via Powermax (Simultaneous heating while cooling technology). The reaction mixture was diluted with saturated aqueous sodium bicarbonate solution (50 mL) and extracted with CHCl3 (3×100 mL). The organic extracts were combined and dried over Na2SO4. The solution was filtered and concentrated to give crude product as a yellow oil. This was purified by chromatography through a SiliCycle SiliaSep pre-packed silica gel column (330 gram) using a gradient of 0-100% ethyl acetate/hexanes over 40 min, followed by a gradient of 1-20% methanol/dichloromethane over 30 min to give a tan oil. This was triturated with DCM and diethyl ether and the mixture was filtered. The filtrate was concentrated to give 4-(2-fluoro-5-(morpholinomethyl)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (2.615 g, 4.80 mmol, 23% yield) as a light-yellow oil. 1H NMR (400 MHz, CDCl3) δ 8.13 (d, J=1.56 Hz, 1H); 7.79 (td, J=7.97, 2.05 Hz, 1H); 7.22 (dd, J=8.61, 7.04 Hz, 4H); 6.81-6.92 (m, 4H); 4.82 (d, J=3.33 Hz, 2H); 3.76-3.86 (m, 4H); 3.70 (ddd, J=9.54, 4.99, 4.84 Hz, 4H); 3.45-3.57 (m, 6H); 2.55 (s, 3H); 2.46 (dq, J=12.79, 4.41 Hz, 4H). m/z (ESI, +ve ion) 545.2 (M+H)+.
