Procedure

1,2-Di(benzyloxyacetamido)-3,4,5-trimethoxybenzene (1.9 g) was dissolved in xylene (30 mL), p-toluenesulfonic acid monohydrate (2.0 g) was added to the solution, and the mixture was stirred for 3 hours under reflux. After cooling, methanol saturated with ammonia was added to the reaction mixture into a uniform solution. The solution was concentrated under reduced pressure, and the residue was purified by column chromatography on silica gel (chloroform:methanol=15:1 to 10:1) to obtain the title compound.
