YieldReaction ConditionsOperation in experiment
100% With potassium carbonate; In acetone; for 2h;Heating / reflux; Example 22 4-(5-Chloro-thiophen-2-ylmethoxy)-2-(2,6-dioxo-piperidin-3-yl)-isoindole-l,3-dioneStep 1 :[226] To a stirred suspension of 3-hydroxyphthalic acid dimethyl ester (1.4 g, 6.8 mmol) in acetone (70 mL) and potassium carbonate (2.8 g, 20 mmol) was added 2-chloro-5- chloromethyl-thiophene (0.83 mL, 7.1 mmol) and refluxed for two hours. The solvent was evaporated and the residue was partitioned between water (100 mL) and ethyl acetate (150 mL) and washed with water (2 x 100 mL). The combined organic phases was dried, concentrated and purified by flash column chromatography (EtOAc/Hexane) to give 3-(5- chloro-thiophen-2-ylmethoxy)-phthalic acid dimethyl ester (2.3 g, 100% crude yield). The product was used in the next step without further purification.

YieldReaction ConditionsOperation in experiment
48% With triphenylphosphine on polystyrene; di-isopropyl azodicarboxylate; In tetrahydrofuran; at 0 - 20℃; Example 7 4-(3,5-Dichloro-benzyloxy)-2-(2,6-dioxo-piperidin-3-yl)-isoindole-l,3-dioneStep 1 :[181] To a stirred suspension of 3-hydroxyphthalic acid dimethyl ester (0.5 g, 2.4 mmol), <strong>[60211-57-6](3,5-dichloro-phenyl)-methanol</strong> (0.84 g, 4.8 mmol), and polymer-supported triphenyl phosphine (1.5 g, 4.8 mmol) in THF (30 mL) in ice-bath was slowly added diisopropyl azodicarboxylate (1.0 mL, 4.8 mmol) and stirred at r.t. overnight. The mixture was filtered and the solid was washed with ethyl acetate (10 mL). The filtrate was evaporated and the residue was purified by flash column chromatography (EtOAc/Hexane) to give 3-(3,5-dichloro-benzyloxy)-phthalic acid dimethyl ester (0.42 g, 48% yield). The product was used in the next step without further purification.
