実験手順
To 0.2 g of pulverized 2-(3-carbamoylphenylamino)-N-(3,4-dimethoxyphenethyl)acetamide was added 100 ml of water and the mixture was stirred at 60° to 65° C. for 30 minutes to dissolve the powder completely. The solution was then concentrated under reduced pressure at 60° C. until about 40 ml of residual liquid was left, and allowed to stand at room temperature overnight. The colorless needles precipitated were collected by filtration, washed with water and then air-dried by allowing to stand at room temperature to obtain 0.13 g of 2-(3-carbamoylphenylamino)-N-(3,4-dimethoxyphenethyl)acetamide trihydrate having a melting point of 54°-57° C.
