二(2,4,6-三氯苯基)2-苄基丙二酸二乙酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of ethyl 4-aminobenzoate (2.85 g, 17.2 mmol) and bis(2,4,6-trichlorophenyl) 2-benzylmalonate (11.4 g, 20.7 mmol, Intermediate 33: step a) was microwaved at 250° C. for 15 minutes (Biotage Initiator). The reaction was then allowed to cool to room temperature, and the resulting tan semisolid was dispersed in ether (15 mL) and filtered. The beige filter cake was washed with ether (1×15 mL) and dried at 100° C. to provide the title compound as a light beige powder. step a) was microwaved at 250° C. for 15 minutes (Biotage Initiator) filtered The beige filter cake was washed with ether (1×15 mL) dried at 100° C.

反应条件: temp:105.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 2-benzylmalonic acid (10.0 g, 51.5 mmol), 2,4,6-trichlorophenol (20.3 g, 103 mmol), and POCl3 (12.0 mL, 129 mmol) was stirred under air at 105° C. for 2 hours. The reaction was then cooled to room temperature, poured on 150 mL ice, and extracted with 4:1 ether/DCM (3×150 mL). The combined organic layers were washed with water (1×400 mL) and 4 M aqueous NaCl (1×100 mL), and the yellow organic layer was dried (Na2SO4), filtered, and concentrated by rotary evaporation at <40° C. to provide the title compound as a tan thick oil that became a beige solid upon standing. The reaction was then cooled to room temperature extracted with 4:1 ether/DCM (3×150 mL) The combined organic layers were washed with water (1×400 mL) and 4 M aqueous NaCl (1×100 mL) the yellow organic layer was dried (Na2SO4) filtered concentrated by rotary evaporation at <40° C.
