반응 단계
A mixture of thiourea (4.95 g, 65.0 mmol) and dimethoxymethyl-dimethyl-amine (23.2 g, 195 mmol) in methanol (80 mL) was heated at reflux for 30 minutes. After allowing the mixture to cool, triethylamine (19.8 g, 195 mmol) and a solution of 2-bromo-1-(chloro-phenyl)-ethanone (crude from last step) in methanol (50 mL) were added. The mixture was heated at reflux for 4 hours. The solvent was removed and the residue was used directly in the next procedure.
