YieldReaction ConditionsOperation in experiment
9.6% With chlorosulfonic acid at 0℃; for 1.5h; 158.4 Step 4: 158e (9.0 g, 38.5 mmol) was added portionwise to chlorosulfonic acid (100 mL) while cooling with an iced bath. See Figure 4. The resulting miture was stirred at 0°C for 1.5h, poured into ice-water (1 L), and extracted with EtOAc (200 mL x3). The organic layers were dried over anhydrous sodium sulfate and concentrated. The residue was purified with by column chromatography on silica gel (ethyl acetate: petroleum ether = 1 : 3) to afford 5- (trifluoromethoxy)-2,3-dihydro-lH-inden-l-one 158f (800 mg, 9.6%) as a yellow solid. FontWeight="Bold" FontSize="10" H NMR (400 MHz, CDC13): δ 7.72 (d, / = 8.4 Hz, 1H), 7.24 (s, 1H), 7.14 (d, / = 8.4 Hz, 1H), 3.11 (t, / = 5.6 Hz, 2H), 2.69 - 2.66 (m, 2H).
With trifluorormethanesulfonic acid at 5 - 20℃; for 18h;
With trifluorormethanesulfonic acid 20.2 3-(3-Trifluoromethoxy-phenyl)-propionic acid Step 2 5-Trifluoromethoxy-indan-1-one About 37 ml of trifluoromethanesulfonic acid were added at about 5° C., with stirring, to 12.4 g of the product from step 1, and stirring was then carried out for 18 hours at room temperature. Crushed ice was then added, followed by extraction with diethyl ether. The combined organic phases were washed with saturated sodium hydrogen carbonate solution, water and saturated sodium chloride solution, and dried over magnesium sulfate, filtered and concentrated in vacuo at from 25 to 40° C. (yield 10.1 g).
With trifluorormethanesulfonic acid at 5 - 20℃; for 17h; 55.55A 5-(trifluoromethoxy)-2,3-dihydro-1H-inden-1-one A solution of 3-(3-(trifluoromethoxy)phenyl)propanoic acid (12.4 g, 0.053 mmol) was diluted with trifluoromethanesulfonic acid (37 mL) at 5° C. and then left to stir at room temperature for 17 hours. The mixture was then concentrated under reduced pressure and the crude oil was dissolved in diethyl ether, and washed with an aqueous solution of 1M potassium carbonate, then with water and brine, dried (MgSO4), filtered, and concentrated under reduced pressure to provide the title compound. 1H NMR (400 MHz, DMSO-d6) δ ppm 7.76 (dd, J=0.3, 8.4 Hz, 1H), 7.60 (s, 1H), 7.41-7.37 (m, 1H), 3.17-3.13 (m, 2H), 2.70-2.67 (m, 2H).
With PPA at 80℃; for 12h; 211 The mixture of Compound 211D (8.5 g, 36 mmol) in PPA (30 mL) was stirred at80 °C for 12 hours. The mixture was quenched with ice-water (100 mL), adjusted to pH 8 with saturated NaHCCh solution, and extracted with ethyl acetate (100 mL x 3). The combined organic layers was dried over anhydrous sodium sulfate, filtered, concentrated, and purified with flash column chromatography on silica gel (ethyl acetate in petroleum ether, 20% v/v) to afford Compound 211E. LC-MS (ESI) m/z: 217 [M+H]+; 1H-NMR (CDCh, 500 MHz): d (ppm) 2.73-2.76 (m, 2H), 3.17-3.19 (m, 2H), 7.21 (dd, J= 7.2, 2.0 Hz, 1H), 7.28 (d, J= 2.0 Hz, 1H), 7.79 (d, J= 7.2 Hz, 1H).
With polyphosphoric acid at 80℃; for 12h; 211 The mixture of Compound 211D (8.5 g, 36 mmol) in PPA (30 mL) was stirred at 80 oC for 12 hours. The mixture was quenched with ice-water (100 mL), adjusted to pH 8 with saturated NaHCO3 solution, and extracted with ethyl acetate (100 mL x 3). The combined organic layers was dried over anhydrous sodium sulfate, filtered, concentrated, and purified with flash column chromatography on silica gel (ethyl acetate in petroleum ether, 20% v/v) to afford Compound 211E. LC-MS (ESI) m/z: 217 [M+H]+; 1H-NMR (CDCl3, 500 MHz): d (ppm) 2.73- 2.76 (m, 2H), 3.17-3.19 (m, 2H), 7.21 (dd, J = 7.2, 2.0 Hz, 1H), 7.28 (d, J = 2.0 Hz, 1H), 7.79 (d, J = 7.2 Hz, 1H).
