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

实验步骤: To a reaction mixture of 3-[1-(3,5-dimethyl-1H-pyrrol-2-yl)-meth-(Z)-ylidene]-2-oxo-2,3-dihydro-indole-1-carbonyl chloride (150 mg, 0.5 mmol) and 3-pyrrolidin-1-yl-propane-1,2-diol (88 mg, 0.6 mmol) in 3.0 mL of THF was added 80 μl of pyridine dropwise at room temperature. Upon addition, the reaction mixture was stirred at room temperature for 20 min., and filtered. The orange solid was then washed with ethyl acetate and hexane sequentially and dried in a vacuum oven overnight to give 3-[1-(3,5-dimethyl-1H-pyrrol-2-yl)-meth-(Z)-ylidene]-2-oxo-2,3-dihydro-indole-1-carboxylic acid 2-hydroxy-3-pyrrolidin-1-yl-propyl ester as an orange solid. 1HNMR (400 MHz, CDCl3 and 2 drops of DMSO-d6) δ 12.63 (s, br, 1H, NH-1′), 11.77 (s, br, 1H, OH), 7.86-7.88 (m, 1H), 7.51-7.53 (m, 1H), 7.42 (s, 1H, H-vinyl), 7.18-7.25 (m, 2H), 6.06 (d, J=2.3 Hz, 1H, H-4′), 4.65-4.73 (m, 2H), 4.44-4.56 (m, 2H), 3.91-3.93 (m, 1H), 3.33-3.52 (m, 2H), 2.88-3.15 (m, 2H), 2.40 (s, 3H, CH3), 2.36 (s, 3H, CH3), and 2.01-2.32 (m, 4H).
