実験手順
0.04 mol of N-methyl-N-benzylamine and 0.02 mol of 3-methyl-6-(2-bromoethyl)benzothiazolinone, the latter being dissolved beforehand in 120 cm3 of dioxane, are introduced into a 100-cm3 ground-necked flask fitted with a reflux condenser. The mixture is heated to reflux for 96 hours with magnetic stirring. After cooling, the reaction mixture is filtered and the filtrate is then evaporated on a water bath under vacuum. The residue is taken up with 50 cm3 and alkalinized with 10 cm3 of normal sodium hydroxide solution.
