Procedure

A solution of 4-(5-chloro-2-fluoropyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (0.723 g, 1.51 mmol) and tert-butyl 5-aminopyridin-2-ylcarbamate (Example 190, Step 2, 0.317 g, 1.52 mmol) in THF (5 mL) was treated dropwise with LiHMDS (4.52 mL, 4.52 mmol) at 0° C. The dark red mixture was stirred at 0° C. for 30 min. Water (0.2 mL) was added to quench the reaction. The reaction mixture was partitioned between saturated aqueous ammonium chloride (40 mL) and EtOAc (40 mL). The aqueous phase was extracted with EtOAc (20 mL). The combined organic phases were dried over sodium sulfate, filtered and concentrated in vacuo. The crude product was purified by column chromatography (50 g, eluent: EtOAc in hexanes 0%-35%) to give tert-butyl 5-(3-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-5-chloropyridin-2-ylamino)pyridin-2-ylcarbamate (0.697 g, 69% yield) as a yellow foam. 1H NMR (300 MHz, CDCl3) δ 11.77 (s, 1H); 8.74 (d, J=2.34 Hz, 1H); 8.39 (br. s., 1H); 8.22 (s, 1H); 7.79-7.94 (m, 2H); 7.28 (br. s., 1H); 7.19 (t, J=9.28 Hz, 4H); 6.86 (dd, J=8.18, 3.95 Hz, 4H); 4.83 (d, J=11.55 Hz, 4H); 3.80 (d, J=4.97 Hz, 6H); 2.58 (s, 3H); 1.53 (s, 9H). m/z (ESI, +ve ion) 669.2 (M+H)+.
