A mixture of 4-chloro-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (312 mg, 0.811 mmol), 2-fluoro-5-(thiomorpholinomethyl)pyridin-3-ylboronic acid (249 mg, 0.973 mmol), Am-Phos (40 mg, 0.057 mmol), and potassium acetate (239 mg, 2.432 mmol) in EtOH (3.5 mL) and water (1.5 mL) was heated in a microwave at 100° C. for 30 min. The mixture was partitioned between EtOAc (20 mL) and 1 N NaOH (3 mL). The separated EtOAc layer was washed with brine, concentrated and purified on a Redi-Sep pre-packed silica gel column (40 g) eluting with a gradient of 30-70% EtOAc in hexanes to give 4-(2-fluoro-5-(thiomorpholinomethyl)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (306 mg, 67.3% yield) as a yellow viscous oil. 1H NMR (400 MHz) δ 8.47 (dd, J=9.3, 1.9 Hz, 1H); 8.28 (s, 1H); 7.24 (d, J=8.4 Hz, 4H); 6.90 (t, J=8.5 Hz, 4H); 4.76 (d, J=4.9Hz, 4H); 3.74 (s, 3H); 3.73 (s, 3H); 3.60 (s, 2H); 2.66-2.58 (m, 8H); 2.47 (s, 3H). m/z (ESI, +ve ion) 561 (M+H)+.
