65% With thionyl chloride; triethylamine; In dichloromethane; EXAMPLE 8 N-Methyl-N-(4-trifluoromethyl-phenyl)-1,2-dihydro-4-hydroxy-5-methoxy-1-methyl-2-oxo-quinoline-3-carboxamide (Method B) To an ice-cold solution of 1,2-dihydro-4-hydroxy-5-methoxy-1-methyl-2-oxo-quinoline-3-carboxylic acid (8 g, 0.032 mol), triethylamine (15.5 ml, 0.11 mol) and 4-trifluoromethyl-N-methylaniline (6.1 g, 0.035 mol) in 150 ml of methylene chloride was added dropwise during 0.5 hours a solution of thionyl chloride (3.0 ml, 0.042 mol) in 10 ml of methylene chloride. The stirring was continued at 4° C. for 4 hours. The solution was diluted with 10 ml of methylene chloride, washed with cold 1 M sulphuric acid and then extracted with 1 M sodium hydroxide. The pH of the aqueous phase was adjusted to 8-8.5, clarified by filtration and then acidified with hydrochloric acid to pH 4. On standing a crystalline precipitate was formed which was filtered off, washed with water and dried to give the title compound (8.5 g) yield 65percent. 1H NMR (CDCl3) delta 3.48 (3H, s), 3.54 (3H, s), 4.06 (3H, s), 6.70 (1H, d), 6.94 (1H, d), 7.46 (1H, t), 7.50 (4H, broad signal). 13C NMR (CDCl3) delta 29.8 (CH3), 36.9 (CH3), 56.9 (CH3), 103.5 (CH), 104.2 (C), 108.7 (CH), 109.5 (C), 117.3+121.7+126.0+130.3 (C), 125.8+125.9+125.9+126.0 (CH), 126.3 (CH), 127.9+128.4+128.9+129.4 (C), 131.8 (CH), 141.4 (C), 146.7 (C), 157.2 (C), 158.0 (C), 160.3 (C), 165.0 (C); some peaks are multiplets due to F-coupling.

YieldReaction ConditionsOperation in experiment
99% In octane; for 2.0h;Reflux; Molecular sieve;Product distribution / selectivity; A mixture of 11 (5.00 g, 18.9 mmol), N-methyl-p-trifluoromethylaniline (5.13 g, 28.4 mmol) and n-octane (200 mL) were refluxed in a Soxhlet extraction apparatus containing 4A molecular sieves (22.9 g) for 2 hours. After cooling the mixture the product was isolated as above to furnish 7.6 g (99 percent) of 4-hydroxy-5-methoxy-N,l-dimethyl-2-oxo-N-[(4- trifluoromethyl)phenyl] - 1 ,2-dihydroquino line-3 -carboxamide (C) . 1 H-NMR analysis on the isolated product revealed no impurities other than 1 molpercent remaining ester 11. 1 H-NMR (CDCI3) 9.9 (s, 1H), 7.50 (bs, 4H), 7.46 (t, 1H), 6.94 (d, 1H), 6.70 (d, 1H), 4.06 (s, 3H), 3.54 (s, 3H), 3.48 (s, 3H). When the same reaction was performed by the traditional distillation from n-octane (Entry 26) during 2 hours according to prior art US patent No. 6,875,869 the product was isolated in 94 percent yield and determined by 1H-NMR analysis to consist of a mixture of compound C (96 molpercent) and the starting material 11 (4 molpercent).
