Formic Acid → HCID 10080884, compound

Participants

Reaction Steps

Acetic anhydride (20 ml) was added dropwise to formic acid (60 ml) at room temperature and after the mixture was stirred for 30 minutes, a solution of 2,3,4,5-tetrahydro 1H-2-benzazepine (10.71 g, 72.75 mmol) in ethyl acetate (5 ml) was added dropwise at room temperature. This mixture was stirred for 3 hours, after which it was diluted with ice-water and extracted with ethyl acetate. The extract was washed successively with water, aqueous solution of potassium carbonate (K2CO3), and saturated NaCl/H2O and dried over MgSO4. The solvent was then distilled off under reduced pressure and the residue was purified by silica gel column chromatography (eluent: ethyl acetate) to provide the title compound (11.35 g) as colorless oil.
