Abstract

A number of 2-substituted benzothiazoles with 2-furyl- (Figure
1.) or 3-furyl- (Figure 2.) group as a substituent were prepared
by the oxidative cyclization of corresponding thioanilides. Some of
the prepared benzothiazoles were converted to N-methyl derivatives
with dimethylsulphate. The compounds were isolated as quarternary
salts. The influence of substituents on the basicity of the benzothiazole
nucleus and on the rate of quarternization was established.
