93% | With sodium acetate; In water; at 100℃; for 18h; | EXAMPLE 37 (FROM TABLE 1) 5-Bromo-2-oxo-1,2-dihydroindol-3-ylidenemethyl)-2-isopropyl-4-phenyl-1H-pyrrole-3-carboxylic Acid (3-diethylaminopropyl)amide A mixture of 2-aminoacetophenone hydrochloride (1 equiv.), ethyl isobutylacetate (1.2 equiv.) and sodium acetate (2.4 equiv.) in H2O was stirred at 100 C. for 18 hours and then cooled to room temperature. The aqueous layer was decanted off and the oil was dissolved in ethyl acetate. It was then washed with water and brine and then dried to give (93%) of 2-isopropyl-4-phenyl-1H-pyrrole-3-carboxylic acid ethyl ester as a red brown oil. 1H NMR (300 MHz, DMSO-d6) delta 11.21 (s, br, 1H, NH), 7.14-7.27 (m, 5H), 6.70 (d, J=2.7 Hz, 1H), 4.02 (q, J=7.1 Hz, 2H, OCH2CH3), 3.65 (m, 1H, CH(CH3)2), 1.22 (d, J=7.5 Hz, 6H, CH(CH3)2), 1.04 (t, J=7.1 Hz, 3H, OCH2CH3).

In pyridine; | Example 80 2-acetaminoacetophenone To a solution of 2-aminoacetophenone hydrochloride (2.0 g) in pyridine (20 ml) was added dropwise acetyl chloride (0.829 ml), and the mixture was refluxed for 20 min. The reaction mixture was poured into ice water, and the mixture was extracted with ethyl acetate. The organic layer was washed successively with 50% aqueous potassium hydrogensulfate solution, saturated aqueous sodium hydrogencarbonate solution and saturated brine, dried over sodium sulfate and purified by silica gel column chromatography to give the title compound (1.180 g). |
