HCID 57428083Methanesulfonic acid 5-[3-(4-chloro-phenyl)-benzo[d]isothiazol-6-yl]-pent-4-ynyl ester

Procedure

In analogy to example 15.1, 5-[3-(4-Chloro-phenyl)-benzo[d]isothiazol-6-yl]-pent-4-yn-1-ol and methane sulfonyl chloride were converted to yield Methanesulfonic acid 5-[3-(4-chloro-phenyl)-benzo[d]isothiazol-6-yl]-pent-4-ynyl ester as a light yellow oil, MS: 405 (M, 1Cl).
