Versuchsvorschrift

4-Bromo-3-methylthiobenzamide (D38, 0.87 g, 0.0038 mole) was dissolved in ethanol (60 ml) and treated with chloroacetone (0.39 ml, 0.0049 mole). The reaction mixture was heated under reflux for 5 h, then more chloroacetone (0.39 ml, 0.0049 mole) was added and the mixture heated under reflux for a further 3 h. After cooling to room temperature, the solvent was removed in vacuo to leave the title compound as a pale oil (1.00 g, 98%).
