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 30-40% ethylamine in methanol to give 2-{2-[3-(2,6-difluorophenyl)-2,2-dioxido-2,1,3-benzothiadiazol-1(3H)-yl]ethoxy}-N-ethylethanamine which was treated with 1N hydrochloric acid in ether to give its hydrochloride salt as a white solid (0.67 g, 67%). HRMS: calcd for C18H21F2N3O3S+H+, 398.13444; found (ESI, [M+H]+Obs'd), 398.1341.
