Roxatidine acetate is a specific and competitive histamine H2 receptor antagonist drug that is used to treat gastric ulcers, Zollinger–Ellison syndrome, erosive esophagitis, gastro-oesophageal reflux disease, and gastritis.[1][2]
Pharmacodynamic studies showed that 150 mg of roxatidine acetate were optimal in suppressing gastric acid secretion, and that a single bedtime dose of 150 mg was more effective than a dose of 75 mg twice daily in terms of inhibiting nocturnal acid secretion.[1]
It was patented in 1979 and approved for medical use in 1986.[3] It is available in countries including China, Japan, Korea, Germany, Italy, the Netherlands, Greece and South Africa.[2]
The reductive amination between piperidine [110-89-4] (1) and 3-hydroxybenzaldehyde [100-83-4] (2) gives 3-(1-Piperidinylmethyl)phenol [73279-04-6] (3). William ether synthesis with N-(3-Bromopropyl)phthalimide [5460-29-7] (4) gives PC12898565 (5). W.K. deprotection with hydrazine yielded (3-(1-piperidinylmethyl)phenoxy)propylamine [73278-98-5] (6). Heating with glycolic acid [79-14-1] (7) gave the amide (8). Acetylation with acetic anhydride completed the synthesis of (9).
