Procedure

To a solution of 4-(1H-pyrazol-4-yl)-7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]-pyrimidine (309 mg, 0.980 mmol) in ACN (6 mL) was added 2-cyclohexen-1-one (190 μL, 01.96 mmol), followed by DBU (40 μL, 0.3 mmol). The resulting mixture was stirred for one hour at which point LCMS indicated complete addition. The mixture was reduced in vacuo and the crude product was purified by column chromatography to obtain the product (397 mg, 98%). 1H NMR (400 MHz, CDCl3): δ 8.84 (s, 1H), 8.27 (s, 1H), 8.25 (s, 1H), 7.45 (d, 1H), 6.79 (d, 1H), 5.67 (s, 2H), 4.61 (m, 1H), 3.55 (m, 2H), 3.05-2.90 (m, 2H), 2.45-2.30 (m, 4H), 2.05 (m, 1H), 1.90 (m, 1H), 0.92 (m, 2H), −0.06 (s, 9H). MS (EI) m/z=412.2 (M+H).
