YieldReaction ConditionsOperation in experiment
98% With thionyl chloride; at 20℃;Cooling with ice; 3-Bromo-5-aminobenzoic acid 12 (1.0 g, 4.62 mmol) was stirred in methanol (15mL) with ice cooling, and the yellow solution was treated with thionyl chloride (4.00 mL, 55.0 mmol) dropwise over 20 mm. The resulting mixture was allowed to warm up to room temperature and left stirring overnight. The reaction mixture was quenched with aqueous saturated NaHCO3 solution at 0 C. The solvent was then removed under vacuum, and the residue was suspended in ethyl acetate (200 mL). The organic phase was washed with brine (100 mL), dried (Na2504) and concentrated to afford the title compound as a yellow solid (1.08 g, 98%). ?H NMR (400 MHz, Methanol-d) oe 7.10 (t, J 1.6 Hz, 1H), 6.83 (t, J 1.6 Hz, 1H), 6.57 (t, J= 1.6 Hz, 1H), 3.46 (s, 3H). 13C NMR (100 MHz, CDC13) oe: 52.3, 114.6, 121.6, 122.3, 122.9, 132.6, 147.7, 166.0. m/z (ESI, MH) 231. ESI-HRMS (MH) calcd. for C8H8BrNO2 229.9817, found 229.9818. HPLC purity 98.8 % (R= 12.3 mm).
98% With thionyl chloride; at 20℃; for 15h;Cooling with ice; 3-Bromo-5-aminobenzoic acid (61a, 1.01 g, 4.62 mmol) was stirred in methanol ( 15 mL) with ice cooling, and the yellow solution was treated with thionyl chloride (4.00 mL, 55.0 mmol) dropwise over 20 min. The resulting mixture was warm up to room temperature and left stirring for 15 h. The reaction mixture was quenched with aqueous saturated (0564) NaHCOs solution at 0 C. The solvent was then removed under vacuum, and the residue was suspended in ethyl acetate (200 mL). The organic phase was washed with brine (100 mL), dried (Na2SOi) and concentrated in vacuo to afford the title compound 61b (1.08 g, 98%) as a yellow solid; NMR (400 MHz, DMS0 ) d 7.16 (dd, J =1.48, 2.12 Hz, 1H), 7.13 (t, J =1.64 Hz, 1H), 6.96 (t, J =2.00 Hz, 1H), 5.74 (s, 2H), 3.81 (s, 3H); MS (ESI, m/z) 231 (0565) [M+l]+; ESI-HRMS calcd. m/z for C8H8BrN02 229.9817, found 229.9818 [M+l]+
91% With thionyl chloride; at 0℃; for 24h;Reflux; General procedure: A solution of the appropriate 2-aminobenzoic acid (1equiv) in MeOH was cooled to 0C followed by a dropwise addition of thionyl chloride (2.5equiv). The mixture was refluxed for 24h. After evaporation of the solvent and neutralization by addition of a saturated aqueous NaHCO3 solution, the mixture was extracted with EtOAc and the combined organic layers were dried over MgSO4. Purification by CC (n-hexane/EtOAc) provided the title compounds.
