To a stirred solution of 3.0 g (0.017 mol) of N-(2-fluorophenyl)thiourea in 75 ml of acetone was added an excess of methyl iodide. The reaction was allowed to stir over night. To the solution was then added 20 ml of cyclohexane; a white solid crystallized and was collected by filtration to yield 4.3 g of N-(2-fluorophenyl)-S-methylisothiourea.
