Procedure
LiHMDS (1 M in THF, 1250 μL, 1.250 mmol) was added to a solution of 5-amino-2-methoxypyridine (123 mg, 0.990 mmol) and 4-(5-chloro-2-fluoropyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (190 mg, 0.396 mmol) in THF (5 mL) under nitrogen at rt. A dark orange mixture formed. After 2 h, HCl (5N, 0.3 mL) was added. The mixture was partitioned between EtOAc-water (10 mL each). The aqueous layer was extracted 3× with EtOAc. The combined organic layers were washed with water 3×, NaHCO3 (satd), dried over MgSO4, and concentrated. The residue was purified on silica (10-80% EtOAc in hexane) to give a yellow oil which, upon trituration with MeOH, resulted in a yellow solid (110 mg). LCMS (ES, pos.): calcd for C31H30ClN7O3: 583.2. found: 584.1 (M+H)+. 1H NMR (400 MHz, CDCl3) δ 11.64 (s, 1H); 8.73 (d, J=2.74 Hz, 1H); 8.25 (d, J=2.54 Hz, 1H); 8.19 (d, J=2.74 Hz, 1H); 7.83 (dd, J=9.00, 2.74 Hz, 1H); 7.19 (dd, J=16.43, 8.61 Hz, 4H); 6.78-6.92 (m, 4H); 6.70 (d, J=8.80 Hz, 1H); 4.86 (s, 2H); 4.81 (s, 2H); 3.92 (s, 3H); 3.80 (d, J=9.19 Hz, 6H); 2.57 (s, 3H).
