Procedure

To a stirred solution of 4-(2,4-dichlorophenyl)-2-(2-fluoropyridin-4-yl)-5-formylthiophene-3-carbonitrile (200.0 mg, 0.5302 mmol) in dry MeOH (12 mL, 3.0E2 mmol) was added Potassium carbonate (161 mg, 1.17 mmol) and dimethyl 1-diazo-2-oxopropylphosphonate (132 mg, 0.689 mmol). The mixture was stirred at rt for 2 h. The mixture was quenched by sodium bicarbonate solution and extracted with EtOAc. The organic layer was dried and evaporated. The residue was purified by column chromatography to afford the title compound. LC/MS (A) ES+ 373, 375. 1H NMR (400 MHz, d1-chloroform) δ: 8.39 (1H, d, J=5.29 Hz), 7.61 (2H, ddd, J=6.19, 3.83, 1.68 Hz), 7.45-7.31 (3H, m), 3.49 (1H, s)
