実験手順

A solution of 5-chloro-N-(6-methoxypyridin-3-yl)-3-(2-methyl-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)pyridin-2-amine (0.150 g, 0.332 mmol) and 4-methoxybenzylamine (0.108 mL, 0.830 mmol) (Source: Aldrich) in THF (10 mL) was treated with sodium tert-butoxide (0.096 g, 0.996 mmol) and 2-di-t-butylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (0.030 g). The mixture was deoxygenated and treated with Pd2(dba)3 (0.030 g, 0.033 mmol) under N2. The flask was fitted with a reflux condenser, then placed into a pre-heated bath at 80° C. and stirred overnight. The reaction mixture was diluted with saturated aqueous NaHCO3 (15 mL) and extracted with CH2Cl2 (2×25 mL). The combined organic extracts were washed with NaHCO3 (20 mL) and dried over Na2SO4. The solution was filtered and concentrated in vacuo to give a tan oil. A glass microwave reaction vessel was charged with the crude oil and 1 N aqueous HCl (1.5 mL) in THF (2.5 mL). The reaction mixture was stirred and heated in a Discover model microwave reactor (CEM, Matthews, N.C.) at 100° C. for 8 min (100 watts, Powermax feature on). The mixture was diluted with MeOH, concentrated and neutralized with SiliCycle Si-Carbonate Silica Gel (SiliCycle Inc., Quebec City, Canada) (0.800 g). The mixture was diluted with THF/DCM (1:1) and allowed to stir under inert atmosphere overnight. The mixture was filtered and concentrated. The crude material was adsorbed onto a plug of silica gel and purified by chromatography through a RediSep®, Teledyne ISCO, Lincoln, Nebr., pre-packed silica gel column (40 g), eluting with a gradient of 1% to 15% isopropanol in dichloromethane to give N5-(4-methoxybenzyl)-N2-(6-methoxypyridin-3-yl)-3-(2-methyl-9H-purin-6-yl)pyridine-2,5-diamine (0.020 g, 0.043 mmol, 12.86% yield) as a tan solid.
