To a solution of 4-chloro-N-(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (160 g, 604 mmol) in DMF (800 mL) at 0° C., was added sodium hydride (18.86 g, 786 mmol) slowly over min. 1-(Chloromethyl)-4-methoxybenzene (91 mL, 665 mmol) was slowly added over 15 min. The reaction mixture was stirred at 0-5° C. for 30 min and allowed to warm to room temp 25° C. After 1 h, cold water (2.5 L) was added and the mixture was stirred overnight. The resulting slurry was filtered, washed with water (150 mL, ×2) and dried to afford 4-chloro-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine as a solid (215.3 g, 559 mmol, 93% yield). LCMS (ES, pos.): Cacld for C20H21ClN4O2: 384.1. found: 385.1 (M+H)+. 1H NMR (400 MHz, CDCl3) δ 7.16 (t, J=8.12 Hz, 4H); 6.81-6.95 (m, 4H); 4.74 (s, 2H); 4.69 (s, 2H); 3.81 (s, 6H); 2.45 (s, 3H).
