実験手順

To 4.7 g of 6-pentyl-6-methyl-2-oxo-1,4-oxathiane-3-acetic acid, dissolved in 50 ml of diethyl ether, there is added dropwise, with stirring and ice cooling, ethereal diazomethane solution, until a pale yellow color just remained. After the usual working up, 6-pentyl-6-methyl-2-oxo-1,4-oxathiane-3-acetic acid methyl ester is obtained:
