Versuchsvorschrift

Fifty grams of amoxicillin trihydrate is added in portions, with stirring, to 375 ml. of dimethyl sulfoxide. The mixture is stirred at room temperature for 2 hours, then diluted with 75 ml. of methylene chloride and cooled to 0°-5°. The solid product is collected by filtration, washed with methylene chloride and dried. Analysis shows 3 moles of dimethyl sulfoxide and 0.5 mole of water for each mole of amoxicillin; formula weight = 609.
