Participants

Reaction Steps

To 4.98 g (0.0205 mole) of S-methyl-N-(4-chlorobenzyl)-N-methyl-N′-methylisothiourea prepared in (1) was added 25 ml of nitromethane and the mixture was refluxed for 6.5 hours. The nitromethane was distilled off and the residue was subjected to silica gel (240 g) column chromatography using MeOH—CHCl3 (1:10) as an eluent to give 5.23 g of an orange-colored oil. To this oil were added small amounts of EtOH and ether and the mixture was cooled in a dry ice-acetone bath and triturated to give crystals. After addition of ether, the crystals were collected by filtration, washed with ether and dried. The procedure gave 3.69 g of the title compound as pale yellow cyrstals.
