To a suspension of 7-chloro-3,5-dihydrobenzo[e][1,4]oxazepin-2(1H)-one (3.01 g, 15.2 mmol) in tetrahydrofurane (102 ml) was added 2,4-bis-(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (3.45 g, 8.53 mmol) at room temperature. The reaction mixture was heated at reflux for 4 h. The solvent was evaporated and the residue was crystallized from hot ethanol to give the title compound (1.96 g, 60%) as light yellow solid. MS m/e: 211.6 ([M−H]−).
