Reaction Steps

Prepared according to procedure R using 4-chloro-2-methylaniline (2.22 g, 15.7 mmol), ethyl 2-methyl-3-oxobutanoate (4.08 g, 31.4 mmol) in PPA (6.3 g, 62.8 mmol) and heating at 170° C. for 2 h and at rt overnight. The crude mixture was neutralized to pH 7-8 and the precipitated was filtered. The solid was then dried under high vacuum to give 6-chloro-2,3,8-trimethylquinolin-4-ol as white solid. Mass Spectrum (ESI) m/e=222 (M+1).
