Procedure

A suspension of 2-chloro-12H-dibenzo[d,g][1,3,6]dioxazocine (10.65 g, 43 mmol, described in J. Mol. Struct., 131, 1985, 131-140) and 3-chloropropionyl chloride (6.55 g, 51.6 mmol) in dry toluene (100 ml) was heated at reflux temperature for 5 h. After cooling to room temperature, the reaction mixture was washed with a saturated solution of sodium bicarbonate (50 ml). The organic layer was dried (MgSO4), and evaporated in vacuo, affording 2-chloro-12-(3-chloropropionyl) -12H-dibenzo[d,g][1,3,6]dioxazocine (12.85 g , 88%).
