Method for synthesizing intermediate of high-purity Umeclidinium bromide

The invention discloses a method for synthesizing intermediates 1-(2-chloroethyl) piperidine-4-formate and quinuclidin-4-carboxylic ester of Umeclidinium bromide, and particularly discloses a method for synthesizing an intermediate 1-(2-chloroethyl) piperidine-4-formate and quinuclidin-4-carboxylic ester of Umeclidinium bromide. According to the method, crude products of the intermediates 1-(2-chloroethyl) piperidine-4-formate and quinuclidin-4-carboxylate are purified in a molecular distillation or reduced pressure distillation mode, and the high-purity medical intermediates are obtained. Thepurification cost can be effectively reduced through molecular distillation or vacuum distillation, the yield is improved, and the product purity can reach 99% or above. According to the present invention, with the synthesis method, the 1-(2-chloroethyl) piperidine-4-formate and the quinuclidin-4-carboxylate are prepared, the process route is short, the amplified production is easy, and the yieldis high. The method has the characteristics of novel process, high yield, low cost, high product purity and the like.

A 1 - (2 - chloroethyl) - 4 - piperidine carboxylic acid ester synthetic method

This invention relates to a 1 - (2 - chloroethyl) - 4 - piperidine carboxylic acid ester synthetic method, comprises the following steps, S1, compound I and ethylene oxide in the presence of open generates intermediate II; S2, intermediate II and thionyl chloride to carry out chlorination reaction, generating 1 - (2 - chloroethyl) - 4 - piperidine - a ester; synthetic route scientific, less side reaction, high reaction activity, all raw materials the homogeneous reaction, so that the reaction speed and conversion efficiency increase, the yield of 45% or more, the reaction less by-products, process using raw materials are easy, and the cost is low, no special operation process, high requirements on equipment, environment-friendly, can be large-scale production.

Quinuclidine derivative, method for preparing same and application of quinuclidine derivative
