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).
