Downstream synthetic route of 187669-60-9

187669-60-9 1-(4-(Methylsulfonyl)phenyl)piperazine 735904, apiperazines compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.187669-60-9,1-(4-(Methylsulfonyl)phenyl)piperazine,as a common compound, the synthetic route is as follows.

Step 3: To a solution of 2-(6-bromopyridin-3-yl)-5-chloro-lH-berizimidazole (70mgs 0.227mmol) and l-[4-(meraylsulfonyl)phenyl]piperazine (54.5mgf 0.227mmol) in dry DMA (3mL) was added N,N-diisopropylethylamine (59mg, 0.454mmol). The mixture was heated to 110 C under argon for 16 hours. The mixture was filtered and was purified by reverse phase Prep HPLC using 30-60% C?CN/H2O/0.1%TFA as gradient to give 5-cMoro-2-(6-{4-(4- (methylsulfonyl)phenyl]piperazin-l-yl}pyridin-3-yl)-lH-benzimidazole as the TFA salt. LC-MS (M+H)= 468, 187669-60-9

187669-60-9 1-(4-(Methylsulfonyl)phenyl)piperazine 735904, apiperazines compound, is more and more widely used in various fields.
