実験手順
2 g of 4-methyl-6-cyclohexyl-2-pyrone and 1 g of hydroxylamine were dissolved in a mixture of 1.5 g of 2-aminopyridine and 4.5 g of 2-amino-6-methylpyridine and stored for 9 days at room temperature. After the usual working up, there were obtained 0.79 g (37 %) of 1-hydroxy-4-methyl-6-cyclohexyl-2-pyridone melting at 143° C.
