| titleOfInvention | Preparation method of bilastine intermediate |
| abstract | The invention discloses a preparation method of a Bilastine intermediate, which utilizes the special activity of vinyl sulfate to construct a Bilastine key quaternary carbon unit, avoids the use of high-toxicity materials, improves the operability and reduces the industrial production cost. Meanwhile, the unique property of the intermediate is combined with the original Bilastine synthesis strategy, a new synthesis route is designed, two protective agents are removed in one step, the synthesis steps are reduced, the production cost is reduced, and the expensive catalyst in the prior art is avoided. |
