実験手順
A mixture of cis-4,5-bis-(2-chlorophenyl)imidazolidine-2-thione (32) (10.1 g, 0.0312 mol) and methyl iodide (3.89 mL, 0.0624 mol) in abs. EtOH (15 mL) is heated at 90° C. for 6 h. The reaction mixture is cooled to rt, concentrated in vacuo, and the residue suspended in abs EtOH. The insoluble material is filtered to give 11 g of the product 49.
