Thevessel was sealed and heated to 110 C in a way that duringa period of 10 min 110 C had to be reached using amaximum power of 1000 W. The reaction temperaturethen was maintained for 2 h after which the vessel wasallowed to cool down to room temperature. Purification procedure: After cooling 20.0 cm3 of a 10%potassium carbonate solution was added. The mixture wasextracted three times with 30 cm3 ethyl acetate. Theorganic phase was dried over sodium sulfate and the solventwas evaporated under reduced pressure. Theremaining triethyl phosphonoacetate was removed by distillationin vacuo. The crude product was purified bycolumn chromatography on silica gel using a diethyl ether:light petroleum (40-60) 1: 1 mixture as the eluent. Thewhite crystalline product was then recrystallized fromethanol/water by first dissolving the crude product inethanol and then adding water until the solution misted.For crystallization the solution was placed in the refrigerator.Yield: 50% (0.78 g, 3.08 mmol, for both syntheticprocedures); m.p.: 51-52 C; IR: v = 1711 vs, 1645 m,1582 m, 1547 m, 1458 w, 1400 w, 1365 w, 1323 w,1306 s, 1271 m, 1242 w, 1189 s, 1177vs, 1034 m, 997 s,845 s, 789 vs, 743 s, 600 m, 571 m, 492 m cm-1; MS(EI): m/z (%) = 254.1 (30) [M?], 225.2 (10) [M?-C2H5 ],210.2 (60) [M?-C2H4O], 182.4 (100) [M?-CO2C2H5 ,?H?]; 1H NMR (CDCl3, 600 MHz, 298 K): d = 1.34(CH3, 3H, t, J = 7.1 Hz), 4.28 (CH2, 2H, q, J = 7.1 Hz),6.72 (=CH, 1H, d, J = 15.9 Hz), 7.33 (=CHar, 1H, ddd,J = 1.1 Hz, 4.7 Hz, 7.7 Hz), 7.36 (=CHar, 1H, dd,J = 1.6 Hz, 4.9 Hz), 7.68 (=CH, 1H, d, J = 15.9 Hz),7.81 (=CHar, 1H, ddd, J = 1.9 Hz, 7.7 Hz, 8.1 Hz), 8.40(=CHar, 1H, d, J = 8.1 Hz), 8.53 (=CHar, 1H, s), 8.66-8.70(=CHar, 2H, m) ppm; 13C NMR (CDCl3, 150.92 MHz,298 K): d = 14.2 (CH3), 60.8 (CH2), 119.1 (=CHar), 121.1(=CHar), 121.7 (=CHar), 123.0 (=CH), 124.0 (=CHar),136.9 (=CHar), 141.8 (=CH), 142.6 (=Car), 149.2 (=CHar),149.8 (=CHar), 155.5 (=CH), 157.0 (=CH), 166.1 (C=O)ppm.

80% Compound 4 (1.8 g, 7.7 mmol) was dissolved in 20 cm3anhydrous diethyl ether and 20 cm3 anhydrous tolueneunder a nitrogen atmosphere at -78 C. Butyl lithium inhexane (4.0 cm3, 2.5 M) was added dropwise. The solutionwas stirred at -78 C for 90 min before 8.0 cm3 anhydrousdimethyl formamide were added. The resulting solutionwas then stirred for another 90 min at the same temperature.To stop the reaction 50 cm3 of 2 N hydrochloric acidwere added at -78 C and the solution was allowed toreach room temperature. The organic phase was separatedand the aqueous phase was neutralized with diluted sodiumhydroxide solution. A smooth white precipitate wasformed. The aqueous phase was extracted three times withCH2Cl2. The solvent was evaporated under reducedpressure and a light brown oil that solidified to a lightbrown solid was obtained.
