Procedure

To a mixture of potassium carbonate (38.4 mg, 0.278 mmol) in methanol (2.0 mL) at 0° C. was added a solution of 3-cyclopentyl-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]-pyrimidin-4-yl)-1H-pyrazol-1-yl]propanal (prepared as in Example 727, step 4) (61.0 mg, 0.139 mmol) in methanol (1.0 mL), followed by a solution of dimethyl (1-diazo-2-oxopropyl)phosphonate (40.0 mg, 0.208 mmol) in methanol (1.0 mL). The mixture was slowly warmed to ambient temperature and stirred for 16 hours. The mixture was then diluted with water and extracted with ethyl acetate. The combined extracts were washed with water, saturated ammonium chloride, and then dried over sodium sulfate and the solvent was removed in vacuo to afford the product, which was used without further purification (52 mg, 86%).
