Abstract:Vonoprazan important intermediates were prepared in a series of reactions. At first step intermediate 3 was obtained from the reaction of pyrrole with TIPSCl; and then intermediate 3 reacted with Vilsmeier reagents to give intermediate 4; followed by reacted with NBS, intermediate 5 was obtained; Finally, intermediate 5 reacted with 2-fluorophenyl boronic acid by coupling reaction to give the target compound with an overall yield of 35.5%. This process was suitable for industrial production due to the simple procedures, mild reaction conditions and lower cost. |
Key words:anti-acid drug; vonoprazan; Suzuki coupling reaction |
