Procedure
In an analogous manner to Example 11 step 5, 3-(2-bromoethyl)-1-(2-fluorophenyl)-3,4-dihydro-1H-2,1,3-benzothiadiazine 2,2-dioxide (0.96 g, 0.25 mmol) was reacted with cyclopropylamine and then treated with HCl to afford N-{2-[1-(2-fluorophenyl)-2,2-dioxido-1,4-dihydro-3H-2,1,3-benzothiadiazin-3-yl]ethyl}cyclopropanamine as a white solid:
