Procedure

The 2-methyl-3-benzyloxypyridine-4(1H)-one of diacetone xylose is prepared according to the method described in example 2. Starting from 4.50 g (23.8 mmol) of 5-amino-5-desoxy-mono-acetone xylose compound, after re-crystallization in a dichloromethane-ethyl ether mixture, 3.87 g (9.98 mmol) of 2-methyl-3-benzyloxypyridine-4(1H)-one of mono-acetone xylose is isolated, which is pure at chromatographic and NMR analyses. Yield: 42%.
