A mixture of 4-chloro-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (0.150 g, 0.390 mmol), 5-(benzyloxy)-2-fluoropyridin-3-ylboronic acid (0.107 g, 0.432 mmol), Amphos (Aldrich) (0.014 g, 0.020 mmol), potassium acetate (Strem) (0.119 g, 1.22 mmol), EtOH (3 mL), and water (0.3 mL) was sealed under N2 and heated in a microwave at 100° C. for 20 min. The reaction mixture was partitioned between EtOAc and water. The aqueous layer was extracted with EtOAc (2×10 mL). The combined organic layers were dried over MgSO4 and concentrated. The crude product was purified by column chromatography (40 g, 10% to 20% EtOAc in hexanes) to give the product as a white solid (0.090 g). m/z (ESI, +ve ion) 552.0 (M+H)+. 1H NMR (300 MHz, CDCl3) δ 8.17 (d, J=7.31 Hz, 1H); 8.01 (br. s., 1H); 7.31-7.48 (m, 5H); 7.23 (d, J=7.89 Hz, 4H); 6.87 (t, J=7.60 Hz, 4H); 5.13 (s, 2H); 4.81 (d, J=6.28 Hz, 3H); 3.81 (d, J=8.33 Hz, 6H); 2.55 (s, 3H).
