35.1 g | Stage #1: With potassium carbonate In water; acetone at 5℃; for 1 h; Stage #2: at 0 - 20℃; for 1 h; |
By embodiments 2 - 4 prepared in the target product is 40g adding 3000 ml glass reaction in the bottle, sequentially adding potassium carbonate 33.0g, water 220 ml, acetone 350 ml, stirring the temperature to 5 °C, continuing to stir 10 minutes, slowly instillment chlorine formic acid oneself ester 16.0g, after finishing dropping to continue to 5 °C stirring 1 hours, to the reaction solution is added in dichloromethane 1600 ml, up to 28 °C extracting the organic layer, the saturated salt water for 1600 ml washing, the organic layer is dried with anhydrous sodium sulfate, vacuum concentrated solvent to obtain yellowish liquid. Dichloromethane is used for 80 ml dissolved concentrated residual liquid, adding 1000 ml in the reaction flask, lowering the temperature to 0 °C, in 0 °C slow the instillment uses acetone 640 ml of dissolved methanesulfonic acid 7.7g mixed solution, after the completion of the dropping the temperature to room temperature stirring 1 hour, filtering, dichloromethane 320 ml washing, in 40 °C vacuum drying 5 hours, to obtain 35.1g white compound A, HPLC analysis for 99.789percent |
