Reaction Steps

To a solution of (R)-tert-butyl 3-(7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)piperidine-1-carboxylate (1.0 g, 2.1 mmol) in DMF (5 mL), NaH (60% suspension in mineral oil, 100 mg, 2.5 mmol) was added at 0° C. and the reaction mixture was stirred for 1 h. To the reaction mixture was added allyl bromide (308 mg, 2.12 mmol) and the reaction mixture was stirred for 6 h. The solution was diluted with ice-cooled water and stirred for 15 min, the solution was then extracted with EtOAc, dried over Na2SO4 and concentrated in vacuo to give the crude product that was purified by column chromatography (silica gel, gradient, EtOAc in hexanes) to give (0.9 g, 83%) of the titled compound. 1H NMR (400 MHz, CDCl3): δ 8.42 (s, 1H), 8.06 (d, J=8.0 Hz, 2H), 7.43 (d, J=3.2 Hz, 1H), 7.31 (d, J=8.0 Hz, 2H), 6.57 (d, J=3.2 Hz, 1H), 5.98-5.90 (m, 1H), 5.26-5.19 (m, 2H), 4.62-4.51 (m, 1H), 4.29-4.09 (m, 4H), 2.85 (t, J=11.6 Hz, 1H), 2.68-2.60 (m, 1H), 2.41 (s, 3H), 1.97-1.93 (m, 1H), 1.83-1.72 (m, 2H), 1.65-1.58 (m, 1H), 1.42 (s, 9H).
