YieldReaction ConditionsOperation in experiment
With oxalyl dichloride; In dichloromethane; at 20℃; for 1h; 100 mg (0.56 mmol) s5 was suspended in 5 mL CH2Cl2, 0.5 mL (0.27 mmol) oxalyl chloride was added slowly. The mixture was stirred at room temperature for 1 h. Solvent was removed by vacuum distillation, the residue was dissolved in 5 mL CH2Cl2 and added dropwise to a mixture containing 0.6 mmol ethanol, 1.8 mmol triethylamine and 5 mL CH2Cl2. The mixture was stirred at room temperature for another 5 h. Then, the solvent was removed by vacuum distillation, the residue was recrystallized from ethyl acetate and hexane to give white solid 3b 65 mg. Yield44%. mp 104-105C. 1H NMR(400 MHz, CDCl 3 ): d 8.80 (s, 1H, ArH),8.20 (d, 1H, J = 8.4 Hz, ArH), 7.55 (d, 1H, J = 8.8 Hz, ArH), 4.44 (q, 2H,J = 7.2 Hz, OCH 2 ), 4.34 (s, 3H, NCH 3 ), 1.44 (t, 3H, J = 7.2 Hz, CH 3 );13CNMR (100 MHz, CDCl 3 ): d166.1, 145.7, 135.6, 128.2, 126.6, 122.8,108.9, 61.4, 34.4, 14.3.
