With 1,4-diaza-bicyclo[2.2.2]octane; 2-allyloxymethyl-acrylic acid methyl ester; at 50℃; for 2h; | Example 54; Acetic anhydride (87 g) as a derivatizing agent was added dropwise over a period of 1 hour to 371 g of the reaction mixture obtained in Example 53, and the mixture was stirred for 2 hours at 50C. The amount of methyl α-(hydroxyethyl) acrylate in 458 g of this reaction mixture was 2 g. The reaction mixture was then washed with water to remove the catalyst, following which purification was carried out by distillation using a distillation apparatus (theoretical number of plates, 13) and under reduced pressure (operating pressure, 2 kPa). The amount of reaction mixture prior to distillation was 450 g, and included 256 g of methyl α-(allyloxymethyl) acrylate, 1 g of methyl α-(hydroxymethyl) acrylate and 30 g of methyl α-(acetoxymethyl) acrylate. Following distillation, 192 g of product containing 99.3 wt% of methyl α-(allyloxymethyl) acrylate and 0.2 wt% of methyl α-(hydroxymethyl) acrylate was obtained. |

71% | With triethylamine; In dichloromethane; at 0 - 20℃; | Compound lb (232 mg, 2 mmol) was dissolved in 5 mL of DCM with TEA (220 mg, 2 mmol) and cooled to 0 C. To the solution, acetyl chloride (157 mg, 2 mmol) was added dropwise. The reaction mixture was stirred at room temperature after addition. After reaction, the reaction solution was collected by filtration and extracted with water for three times. The organic layers were collected and dried over anhydrous sodium sulfate. The solution was further filtered and concentrated to afford crude product which was subjected to flash chromatography to obtain pure compound 6. Yield: 224.4 mg, 71%. -NMR (400 MHz, CDCh): d 6.36 (s, 1H), 5.85 (s, 2H), 4.81 (s, 2H), 3.79 (s, 3H), 2.10 (s, 3H). 13C-NMR (100 MHz, CDCh): 5(ppm) 170.41, 165.68, 135.21, 127.60, 62.47, 52.06, 20.88. |
