Reaction Steps
A mixture of 2-methylthio-2-imidazoline hydroiodide (1.83 g, 12 mmol) and 3-chloro-4-methyl-phenylhydrazine (1.87 g, 12 mmol) in xylene (10 ml) was heated to 120° C. overnight. After cooling down to room temperature the precipitate is filtered off and re-crystallised from ethanol, white solid, 0.41 g, MS (ISP): 227.3, 225.3 ([M+H]+.).
