Methyl iodide → HCID 21183157, compound

Participants

Reaction Steps

A solution of 2.0 g (7.9 mmol) of 2-methyl-3-(2-methylphenyl)-4-thiocyanoaniline in 15 mL of ethanol was added dropwise over a 20-min period with stirring to a solution of 2.2 g of sodium sulfide nonahydrate (9.1 mmol) in 5 mL of water. The mixture was stirred at ambient temperature for 2 hours and was then cooled with an ice/salt bath. A solution of 1.5 g (11 mmol) of methyl iodide in 5 mL of ethanol was added with stirring over a 10-min period. The mixture was diluted with water and the resulting mixture was extracted with ether. The ethereal extract was washed with water, dried over sodium sulfate, and concentrated by evaporation under reduced pressure. The 2.0 g of residue was the title compound of about 80 percent purity.
