(2S,4R)-4-hydroxypyrrolidine-2-carboxamide;hydrochloride

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 4.50 g of the product obtained in step (1) above were suspended in 45 ml of ethyl acetate and then 14.9 ml of 4.84M hydrogen chloride in ethyl acetate were added under ice-cooling. The mixture was stirred at 25°-30° C. for 30 minutes, after which the reaction mixture was worked up in the same manner as in Preparation 4(2) to give 3.21 g of the title compound. cooling after which the reaction mixture was worked up in the same manner as in Preparation 4(2)
