摘要

Isopropyl methyl [2 - (3-n-propoxy) ethyl] amine, methylphosphate; process for manufacturing such isopropyl methyl [2 - (3-n-propoxy) ethyl] amine, pharmaceutical formulation containing the substance and its use in medicine. Laiso propil met - [2 - (3-n-propoxiphenxi) ethi] amine is an anesthetic force majeure; it is used as an anesthetic for pain treatment,Even local pain 2 - [2 - (3-n-propoxifen oxy) ethyl] amine can be used to introduce the crystallization intermediate into the preparation process of isopropyl methyl [2 - (3-n-propoxifenxi) ethyl] amine. This adds a simple and convenient step in a reaction process where all the other intermediaries are syrup. Such wordsIt avoids distillation of processes that used to take a lot of time and effort. 1. Isopropyl methyl polyphosphate [2 - (3-n-hydroxy) ethyl] ammonia water was separated from an intermediate with high purity, which can be converted into corresponding isopropyl methyl - [2 - (3-n-propoxiphenxi) ethyl] ammonia water at the same time, through simple sliding.
