2'-Fluoroacetophenone - Uses and synthesis methods
Introduction
2 '-fluoroacetophenone is a pharmaceutical intermediate that can be used as a starting material for the synthesis of Vonorazan fumarate. Vonorazan Fumarate, English name: Vonoprazan Fumarate, trade name: Takecab, is a potassium competitive acid blocker developed by Takeda Pharmaceutical Company of Japan, used to treat erosive esophagitis, gastric ulcer, and twelve fingers Intestinal ulcer, Helicobacter pylori eradication, etc. It was listed in Japan on December 26, 2014.
method of synthesis
There are two methods for synthesizing o-fluoroacetophenone. One is the reaction of α-bromoacetophenone with hydrogen fluoride in the presence of pyridine, and the other is the reaction of fluoroacetyl chloride with benzene in the presence of aluminum trichloride. o-fluoroacetophenone can also be obtained, and then the product is refined and purified.
