Reaction Steps

A mixture of compound (f) (1.0 g), 80% methanol (20 ml) and potassium carbonate (1.0 g) was refluxed by heating for 1 hour and evaporated to remove the solvent. The residue was extracted with chloroform. The extract was washed with water, dried, and evaporated to remove the solvent. The residue was applied to column chromatography on silica gel (20 g) to give 2-(2-propynylamino)benzothiazole (g) (829 mg, yield 100%) from chloroform eluate: mp. 134°-135° C. (acetone-hexane).
