摘要:
In a process for preparing isosorbide-5-nitrate, isosorbide is reacted with an aliphatic carboxylic acid, with the formation of an acylation mixture. The acylation mixture is then nitrated, and the resulting nitration mixture is hydrolyzed and/or transesterified in order to split off acyl groups. The product is used in treatment of angina pectoris.
