実験手順
A suspension of 4.6 g (17.5 mmol) of 6-bromo-7-methoxy-2-methyl-quinolin-4-ol in 14.8 ml (158 mmol) of POCl3 was heated at 60° C. for 20 h with stirring. It was then cooled to RT and 50 ml of diethyl ether were added. The solid that precipitated was filtered off by suction and dried in a high vacuum to give 3.85 g of the 6-bromo-4-chloro-7-methoxy-2-methyl-quinoline as a dark brown solid. El mass spectrum, m/e: 287 (M calculated for C11H9BrClNO: 287).
