| titleOfInvention | Novel synthesis route of glipizide |
| abstract | The invention relates to a novel synthesis route of glipizide, which is characterized by comprising the following steps of protecting 4-(2-amino ethyl)benzenesulfonic acid ammonia (II) by Boc anhydride to obtain a compound (III); reacting the compound (III) with cyclohexyl isocyanate to obtain a compound (IV); carrying out deprotection on the compound (IV) to obtain a compound (V); and reacting the compound (V) with 2-methyl-5-pyrazine carboxylic acid to obtain the glipizide (I) with the single impurity which is less than or equal to 0.5% and the high purity which is more than or equal to 99%. The process is simple, the yield is high, the purity is high and the single impurity is low; and the process is environment-friendly and industrial production is easy to realize. |
