Reaction Steps

A mixture of 150 mg (0.52 mmol) 7-tert-butyl-2-hydroxy-4-methyl-quinoline-3-carboxylic acid ethyl ester and POCl3 (1 ml) was heated for 2 h at 150° C. Then the reaction solution was poured into iced water (15 ml) and made alkaline with a saturated aqueous NaHCO3 solution. It was then extracted with EE and the organic phase was washed with brine, dried over Na2SO4, filtered and concentrated to small volume under vacuum. 140 mg (0.46 mmol, 88%) 7-tert-butyl-2-chloro-4-methyl-quinoline-3-carboxylic acid ethyl ester were obtained as the residue, which was reacted further with no additional purification.
