-
Paragraph 0071-0074, (2020/05/13)
The present invention relates to a novel manufacturing method for synthesizing an anti-histamine pharmaceutical medicine, epinastine. The novel manufacturing method for synthesizing epinastine according to the present invention has fewer synthesizing steps than a conventional epinastine manufacturing method, and is a safe synthesis method, thereby being expected to be used for inexpensively synthesizing the anti-histamine pharmaceutical medicine, epinastine by the manufacturing method, and supplying the same to the market.COPYRIGHT KIPO 2020
