実験手順

A solution of MCPBA (1 eq) in chloroform (5 ml) was added to a stirred solution of 10,11-dihydrodibenzo[b,f][1,4] thiazepin-11-one (114 mg, 0.5 mmol) in chloroform (30 ml). After 0.5 hr the reaction mixture was poured into sodium bicarbonate solution (5%, 30 ml), separated and the aqueous layer washed with chloroform (30 ml). The combined organic fractions were dried (MgSO4) and evaporated. Recrystallisation from toluene gave the title compound as off-white crystals (76 mg, m.p. 308°-310° C., Rf 0.16, CH2Cl2 /MeOH 50:1).
