4-Chloro-7-tosyl-7H-pyrrolo[2,3-d]pyrimidine (2 g, 6.37 mmol, 2.00 equiv.) and potassium carbonate (2.7 g, 19.4 mmol, 6.00 equiv.) were added to a solution of (1-benzyl-4-methyl-piperidin-3-yl)-methyl-amine (700 mg, 2.89 mmol, 1.00 equiv.) in water (30 mL). The solution was stirred at about 100° C. for about 16 hours, and then was cooled to ambient temperature. Following standard extractive workup with ethyl acetate (3×100 mL), the crude residue was purified by silica gel column chromatography (ethyl acetate/petroleum (1:1)) to give the title product as a light yellow solid (1.5 g; yield=96%). 1H NMR (300 MHz, CDCl3) δ: 8.36 (s, 1H), 8.08 (d, J=8.4 Hz, 2H), 7.45 (d, J=4.2 Hz, 1H), 7.20-7.42 (m, 7H), 6.75 (d, J=4.2 Hz, 1H), 5.05-5.20 (m, 1H), 3.40-3.65 (m, 5H), 2.70-2.92 (m, 2H), 2.50-2.70 (m, 1H), 2.42 (s, 3H), 2.23-2.42 (m, 1H), 2.10-2.23 (m, 1H), 1.55-1.75 (m, 2H), 0.92 (d, J=6.9 Hz, 3H). LC-MS: m/z=490 (M+H)+.
