Procedure

Dissolve 3-tert-butoxycarbonyl-7-chloro-6-[3-(2-oxo-2,3-dihydro-benzoimidazol-1-yl)-propylthio]-2,3,4,5-tetrahydro-1H-benzo[d]azepine (209 mg, 0.396 mmol) in dichloromethane (10 mL), then add TFA (0.5 mL) dropwise and stir at room temperature overnight. Remove solvents in vacuo then free base using an SCX column, eluting with 7M ammonia in methanol. Concentrate in vacuo, then use a method similar to the General Procedure 2-1 and freeze dry to give the title compound as a solid (140 mg, 70%). MS (ES+) m/z: 388 (M+H)+.
