YieldReaction ConditionsOperation in experiment
88.9% With potassium carbonate; In chloroform; water; at 65 - 80.5℃; for 8.75h; Step 4 To a suspension of 2-hydroxy-1H-indole-2-carboxylic acid ethyl ester (10.08 g, 49.11 mmol) in CHCl3 (200 mL) was added 2-(dimethylamino)ethyl chloride hydrochloride (10.57 g, 73.37 mmol,), potassium carbonate (33.88 g, 245.2 mmol), and water (40 mL) in sequence. The stirred solution was placed in a 65 C. oil bath and the temperature was slowly raised to 80.5 C. over 65 min. After 7 h 40 min, the reaction mixture was cooled to room temperature and the phases were separated. The organic phase was reduced in vacuo to 25% of its original volume. The residue was combined with the aqueous phase and diluted with water and toluene. The organic phase was separated and washed with water and extracted with 1M aqueous HCl. The acidic aqueous phase was washed with toluene, basified by the addition of ~4M aqueous NaOH (55 mL), and extracted with toluene. The organic extract was washed with water, brine, dried over sodium sulfate, and concentrated in vacuo to provide 5-[(2-dimethylamino)ethoxy]-1H-indole-2-carboxylic acid ethyl ester (12.06 g, 88.9%) as an off-white solid.
80% With potassium carbonate; In chloroform; water; at 65 - 80℃; for 17h; Me2N(CH2)2Cl.HCl (1.77 g, 12 mmol), K2CO3(3.40 g, 25 mmol) and water (8 mL) were added to 31 (1.68 g, 8.2 mmol)in CHCl3 (40 mL). The stirred solution was placed in an oil bath at65C. The temperature was slowly raised to 80C during 65 min and themixture was stirred for 16 h at 80C. The organic phase was separated and thesolvent was evaporated to 25% of its original volume. This solution was combinedwith the aqueous phase and diluted with water and toluene. The organic layerwas separated, washed with water and extracted with aq. HCl (1.0 M). The acidicphase was washed (toluene), cooled to 0C, basified (~pH 12) by addition ofaq. NaOH (4.0 M) and extracted (toluene). The extract was washed (water,brine) and dried. Evaporation gave 32 (1.81 g, 80%) as a white solid: mp108-109 (lit.3 mp 110C); IR numax 3315, 1687; 1HNMR d 1.39 (3 H, t, J = 7.1 Hz, OCH2CH3), 2.35 (6 H, s, NMe2),2.76 (2 H, t, J = 5.8 Hz, Me2NCH2CH2), 4.10 (2 H, t, J = 5.8 Hz, Me2NCH2CH2),4.39 (2 H, q, J = 7.1 Hz, OCH2CH3),6.99 (1 H, dd, J = 8.9, 2.4 Hz, 6-H),7.07 (1 H, d, J = 2.4 Hz, 4-H), 7.12(1 H, dd, J = 2.1, 0.8 Hz, 3-H), 7.28(1 H, d, J = 8.9 Hz, 7-H), 9.30 (1 H,s, NH); 13C NMR d14.32 (OCH2CH3),45.83 (NMe2), 58.38 (Me2NCH2CH2), 60.82 (OCH2CH3), 66.57 (Me2NCH2CH2), 103.67 (4-C), 108.13(3-C), 112.69 (7-C), 117.37 (6-C), 127.74 (2-C), 127.89 (3a-C), 132.42 (7a-C),153.83 (5-C), 162.01 (C=O)
