反応手順

Dichloromethane (63 ml; methanol-free) was added to amoxycillin trihydrate (3.5 g; purity by HPLC 86%; water 12.9%) with stirring at room temperature and, then, followed by the addition of 1,2-propanediol (22 ml). The reaction mixture was further stirred for about 20 min at the same temperature. The product was filtered and, then, washed on the filter with dichloromethane (100 ml). Thereafter, the product was suspended in dichloromethane (80 ml) and stirred for about 20 min at room temperature. The resulting suspension was filtered, washed on the filter with dichloromethane (100 ml) and, then, dried under vacuum overnight.
