Procedure

Combine picolinic acid (40 mg, 0.327 mmol), EDC (57 mg, 0.297 mmol) and HOBT (40 mg, 0.297 mmol) in DCM (3 mL). Stir for 10 min at ambient temperature. Add 6-(2-amino-ethoxy)-7-chloro-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine (100 mg, 0.297 mmol). Stir for 16 h at ambient temperature. Dilute with DCM, add water and extract the aqueous layer with DCM. Wash the combined organic extracts with 1M aqueous NaOH and brine. Dry the organic layer over MgSO4 and concentrate in vacuo. Purify by chromatography on silica gel eluting with hexane/EtOAc (3:2) to give 7-chloro-6-{2-[(pyridine-2-carbonyl)-amino]-ethoxy}-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine (94 mg, 74%).
