2-Propargylaminoacetaldehyde → 2-[1-Propargyl-3-(7-bromobenzothiazol-2-yl)ureido]acetaldehyde

Participants

Reaction Steps

7-Bromobenzothiazol-2-yl isocyanate dimer (0.1 mole), the dimethyl acetal of 2-propargylaminoacetaldehyde (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-propargyl-3-(7-bromobenzothiazol-2-yl)ureido]acetaldehyde as the residue.
