実験手順

To a solution of 2,3,4,5-Tetrahydro-1H-benzo[d]azepine hydrochloride (7.0 g) in DCM (200 ml) Et3N (12.1 ml, 2.5 eq) was added followed by a dropwise addition of acetic anhydride (4 ml). After 2 h the mixture was washed in sequence with 1N HCl, 5% aqueous NaHCO3 and brine, then dried over Na2SO4 and concentrated to afford a white solid (6.9 g, 95% yield).
