A mixture of 5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(6-methoxypyridin-3-ylamino)nicotinaldehyde (0.310 g, 0.537 mmol) and (R)-pyrrolidin-3-yl-methanol (0.163 mL, 1.610 mmol) in dichloromethane (0.035 mL, 0.537 mmol) and methanol (0.022 mL, 0.537 mmol) was treated with sodium triacetoxyborohydride (0.341 g, 1.610 mmol). The solution was stirred at room temperature overnight. The crude product was adsorbed onto a plug of silica gel and chromatographed through a Redi-Sep pre-packed silica gel column (40 g) eluting with a gradient of 5% to 10% 2 M NH3.MeOH in CH2Cl2 to give (R)-(1-((5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(6-methoxypyridin-3-ylamino)pyridin-3-yl)methyl)pyrrolidin-3-yl)methanol (0.188 g, 0.284 mmol, 52.9% yield). m/z (ESI, +ve ion) 663.2 (M+H)+.
