Participants

Conditions

Temperature: 40 °C

Procedure

At ambient temperature 1.50 g sodium thiomethoxide are added to a solution of 4.64 g 5-tert-butyl-2-methoxy-3-nitro-benzyl methanesulphonate in 50 ml of 1,4-dioxane. The solution is stirred overnight at 40° C. Then the solvent is removed and the residue is chromatographed on silica gel with cyclohexane/ethyl acetate (98:2→60:40) as eluant.
