Methylvinyl sulphone (2.1 g, 19.78 mmol) and methylamine (33% solution in IMS, 40 ml , excess) were mixed and heated at reflux under a nitrogen atmosphere for 6 hours. After standing overnight at room temperature, the mixture was concentrated in vacuo to give a yellow oil, which was treated with ethereal HCl to give a sticky solid. Trituration with absolute ethanol gave the title compound as a white solid which was collected by filtration and dried at 60° C. in vacuo (1.01 g, 5.82 mmol, 29%); δH [2H6]DMSO 9.27 (2H, br s), 3.59 (2H, dd), 3.31 (2H, dd), 3.12 (3H, s), 2.57 (3H, s).
