Procedure

tert-Butyl 1-methyl-1,3,4,8-tetrahydro-2H-[1,4]oxazepino[6,7-e]indole-2-carboxylate (Intermediate 42, 25 mg, 0.083 mmol) was dissolved in DMF (1 mL) and sodium hydride (60% in mineral oil, 4.0 mg, 0.17 mmol) was added. The reaction mixture was stirred at room temperature for 15 minutes before 2,5-dimethyl-3-thienyl sulfonyl chloride (24 mg, 0.11 mmol) was added. The reaction mixture was allowed to stir at room temperature overnight. The reaction was quenched by addition of water and the crude product was purified by preparative HPLC (XTerra C18, 50 mM NH4HCO3 pH 10-CH3CN) to give tert-butyl 8-[(2,5-dimethyl-3-thienyl)sulfonyl]-1-methyl-1,3,4,8-tetrahydro-2H-[1,4]oxazepino[6,7-e]indole-2-carboxylate (6 mg) which was dissolved in DCM (1 mL) and TFA (1 mL) was added. The reaction mixture was stirred at room temperature for 1 hour and the solvent was removed under reduced pressure. The crude material was purified by preparative HPLC (XTerra C18, 50 mM NH4HCO3 pH 10-CH3CN) to give the title compound (4 mg). MS m/z 377 [M+H]+.
