Procedure

In an analogous manner to general procedure V, 1-[3(bromomethyl)benzyl]-3-(2-fluorophenyl)-1,3-dihydro-2,1,3-benzothiadiazole2,2-dioxide (0.08 g, 0.18 mmol) was treated with methylamine (10 mL) to provide 0.05 g (71%) of 1-(3-{[3-(2-fluorophenyl)-2,2-dioxido-2,1,3-benzothiadiazol-1(3H)-yl]methyl}phenyl)-N-methylmethanamine. HRMS: calcd for C21H20FN3O2S+H+, 398.13330; found (ESI, [M+H]+), 398.1337; HPLC purity 95.4% at 210-370 nm, 7.7 min.; Xterra RP18, 3.5 u, 150×4.6 mm column, 1.2 mL/min, 85/15-5/95 (Ammon. Form. Buff. Ph=3.5/ACN+MeOH) for 10 min, hold 4 min.
