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 methyl isocyanate (0.9 g) was dropwise added to the solution, the resultant was stirred for 15 hours at 30° C. Pyridine was evaporated off under vacuum from the reaction mixture and the residue was recrystallized from methanol to yield the title compound as colorless crystals (2.7 g). mp 202°-203° C.
