Reaction Steps

In an analogous manner to Example 11 step 5, 3-(4-bromobutyl)-1-(2-fluorophenyl)-3,4-dihydro-1H-2,1,3-benzothiadiazine 2,2-dioxide (0.11 g, 0.26 mmol) was reacted to methylamine and then treated with HCl to provide 4-[1-(2-fluorophenyl)-2,2-dioxido-1,4-dihydro-3H-2,1,3-benzothiadiazin-3-yl]-N-methylbutan-1-amine (0.078 g, 82%) as a white solid:
