실험 절차

50 parts by weight of 1-trimethylsilyl-imidazolidine-2-thione in 150 parts by volume of methylene chloride were treated with 35 parts by weight of phosgene in 50 parts by volume of methylene chloride over the course of 2 hours at 0°C. The mixture was stirred for 24 hours at 0°C, the methylene chloride was subsequently stripped off, and the residue was dried in a high vacuum. Semi-solid mass, incompletely soluble in acetone. Crude yield: 97% IR bands at 1830, 1590 and 1240 cm-1.
