- reaction solution was cooled again to room temperature, ammonia gas was blown thereinto and stirred for 30 minutes.
- the reaction mixture was partitioned between methylene chloride and water, the aqueous layer was extracted with methylene chloride, and the organic layers were combined and washed with saturated saline.
- Acetic anhydride (518 mg, 0.48 mmol) and a catalytic amount of 4-dimethylaminopyridine were added to a pyridine solution (2 ml) of this mixture, and the mixture was stirred for 30 minutes. The reaction was stopped by adding water to the reaction solution, and the mixture was partitioned between ethyl acetate and water, and the aqueous layer was extracted with ethyl acetate. The organic layers were combined, washed sequentially with diluted hydrochloric acid and saturated saline, and dried over anhydrous sodium sulfate.
- Acetic anhydride (518 mg, 0.48 mmol) and a catalytic amount of 4-dimethylaminopyridine were added to a pyridine solution (5 ml) of this mixture, and the mixture was stirred for 30 minutes. The reaction was stopped by adding water to the reaction solution, and the mixture was partitioned between ethyl acetate and water, and the aqueous layer was extracted with ethyl acetate. The organic layers were combined, washed sequentially with diluted hydrochloric acid and saturated saline, and dried over anhydrous sodium sulfate.
- the spectrum data of the product was the same as in Reference Example 5.
