Novel alpha-chloroketone derivative and process for preparation thereof |
| abstract |
Disclosed is a novel α-chloroketone derivative as a synthesis intermediate of N-cyano-N'-methyl-N"-(2-((5-methyl-1H-imidazol-4-yl)methylthio)ethyl)guanidine (general name: Cimetidine) which shows an action of controlling the secretion of gastric acid and is valuable as a medicine for remedy of a gastric ulcer. This α-chloroketone derivative is prepared by reacting disulfide derivative with sulfuryl chloride and reacting the reaction product with methylvinyl ketone or by reacting a mercapto derivative with 3-chloro-3-buten-2-one. |
