Reaction Steps

A solution of 2-[(t-butylcarbonyl)imino]-3-[3-(trifluoromethyl)phenyl]-5-methylthiazoline (1 g) and 2,4bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4disulfide (2 g) in THF (10 ml) was refluxed for 2 days. After cooling and removal of the solvent under reduced pressure, the concentrated residue was added pottasium hydrogencarbonate. The obtained crystallines were recrystallized to give 0.6 g of 2-[t-butyl(thiocarbonyl)]imino-3-[3-(trifluoromethyl)phenyl]-5-methylthiazoline (Compound No. 3).
