Participants

Reaction Steps

In 5 mL of dichloromethane, 117 mg (0.30 mmol) of 6β-amino-17-cyclopropylmethyl-4,5α-epoxy-3-methoxymethoxy-morphinan-14-ol was dissolved, and 0.04 mL (0.29 mmol) of triethylamine and 79 mg (0.31 mmol) of benzene-1,2-disulfonyl dichloride were added, followed by heating the mixture to reflux for 1 hour. After allowing the reaction solution to cool to room temperature, aqueous saturated sodium hydrogen carbonate solution was added to the reaction mixture, and the resulting mixture was extracted with chloroform. Organic layers were combined, washed with saturated saline, dried over anhydrous magnesium sulfate and concentrated to obtain 192 mg of 2-(17-cyclopropylmethyl-4,5α-epoxy-14-hydroxy-3-methoxymethoxy-morphinan-6β-yl)-benzo[1,3,2]dithiazol-1,1,3,3-tetroxide as a crude product.
