Procedure

In an analogous manner to general procedure V, 1-[2-(2-bromoethoxy)ethyl]-3-(2,6-difluorophenyl)-1,3-dihydro-2,1,3-benzothiadiazole 2,2-dioxide (0.1 g, 0.23 mmol) was treated with cyclopentylamine (2.4 mL, 9.2 mmol) in methanol to give N-(2-{2-[3-(2,6-difluorophenyl)-2,2-dioxido-2,1,3-benzothiadiazol-1(3H)-yl]ethoxy}ethyl)cyclopentanamine which was treated with 1N hydrochloric acid in ether to give its hydrochloride salt as a white soldi (0.94 g, 87%). HRMS: calcd for C21H25F2N3O3S+H+, 438.16574; found (ESI, [M+H]+Obs'd), 438.1652.
