Procedure

A mixture of (+)(2aS,4R)-6-(3-isoxazolyl)-4-(di-n-propylamino)-1,2,2a,3,4,5-hexahydrobenz[cd]indole (180 mg, 0.5 mmol) and 1 g of MnO2 in 40 mL of CH2 Cl2 was sonicated at 50-55 KHz for 2 hr. The reaction mixture warmed to reflux during the time period. The reaction mixture was filtered through a celite pad and the filtrate was concentrated to dryness in vacuo. The residue was chromatographed (flash column, silica gel, ethyl acetate) to provide 50 mg of the isoxazole indole product as an oil.
