실험 절차

5,6-Dichlorobenzothiazol-2-yl isocyanate dimer (0.1 mole), the dimethyl acetal of 2-β-bromoethylaminoacetaldehyde (0.2 mole) and benzene (100 ml) are charged into a glass reaction vessel equipped with a mechanical stirrer and thermometer. The reaction mixture is stirred at ambient temperatures for a period of about one hour. After this time the reaction mixture is filtered, and the filtrate is stripped of solvent to yield the desired product the dimethyl acetal of 2-[1-β-bromoethyl-3-(5,6-dichlorobenzothiazol-2-yl)ureido]-acetaldehyde as the residue.
