Reaction Steps
5-Chloro-3-(4-hydroxypiperidinocarbonylmethyl)benzothiazolin-2-one (3.2 g) was dissolved in dry pyridine (15 ml) and the solution was cooled. After ethyl isocyanate (0.9 g) was dropwise added to the solution, the resultant was stirred for 10 hours at 50° C. Pyridine was evaporated off under vacuum from the reaction mixture and the residue was recrystallized from ethanol to yield the title compound as colorless crystals (3.0 g). mp 210°-211° C.
