Procedure
To a solution of N-{1-[5-(1-methylethyl)-7-(phenylsulfonyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl]-4-piperidinyl}benzamide D9 (140 mg) in THF (2 mL) and MeOH (1 mL) was added cesium carbonate (272 mg, 0.834 mmol) and the mixture stirred for 2 hours. LCMS showed a small amount of starting material so the reaction was stirred for a further 2 hours. The mixture was then partitioned between EtOAc (20 mL) and water (20 mL) and the organic phase washed with water (20 mL) and brine (20 mL) before it was dried (MgSO4), filtered and the solvent removed in vacuo. The crude product was purified by MDAP. The compound-containing fractions were concentrated and dried in a vacuum oven to give E20 (23 mg) as a white solid, 1H NMR (d6-DMSO) δ 11.62 (1H, s), 8.39 (1H, d), 8.26 (1H, s), 7.88 (2H, d), 7.52 (1H, t), 7.46 (2H, t), 7.09 (1H, s), 4.05 (1H, m), 3.90 (2H, d), 3.16 (1H, septet), 3.00 (2H, t), 1.94 (2H, d), 1.77 (2H, ddd), 1.28 (6H, d), MS(ES+) 364 [M+H]+.
