Reaction Steps

A solution of 3-(difluoromethoxy)aniline (0.038 mL, 0.303 mmol) (Aldrich) and 4-(2-fluoropyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (0.090 g, 0.202 mmol) in THF (3.0 mL) at 0° C. was treated with LiHMDS 1.0 M in THF (0.606 mL, 0.606 mmol) (Aldrich) dropwise. The solution was stirred at 0° C. for 1.5 h and was then quenched with a saturated solution of NH4Cl at 0° C. The mixture was extracted with EtOAc (15 mL), dried over MgSO4, filtered and concentrated to give 4-(2-(3-(difluoromethoxy)phenylamino)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (0.121 g, 0.207 mmol, 99% yield) as a brown oil. 1H NMR (400 MHz, CDCl3) δ 12.12 (br. s., 1H); 8.84 (d, J=8.2 Hz, 1H); 8.35 (br. s., 1H); 7.72 (br. s., 1H); 7.31 (d, J=8.4 Hz, 1H); 7.20 (d, J=7.8 Hz, 5H); 7.11 (t, J=8.0 Hz, 4H); 6.84-6.90 (m, 4H); 6.80 (d, J=7.8 Hz, 1H); 6.71 (d, J=8.4 Hz, 1H); 6.65 (br. s., 1H); 6.45-6.54 (m, 10H); 6.42 (br. s., 4H); 6.28 (br. s., 1H); 4.84 (br. s., 4H); 3.80 (d, J=3.5 Hz, 7H); 2.60 (br. s., 3H). m/z (ESI, +ve ion) 585.1 (M+H)+.
