Yield:-
Reaction Conditions:
with acetic acid for 2 h;Heating / reflux;
Steps:
177
To a stirred solution of 2-amino benzoic acid ethyl ester (20 g; 121 mmol) in acetic acid (35 mL) was added 2,5-dimethoxytetrahydrofuran (19 g; 174 mmol). The reaction mixture was stirred for two hours at reflux. After evaporation of the solvent, the crude product was purified by flash column chromatography (methylene chloride) to give compound 2-pyrrol-1-yl-benzoic acid ethyl ester as a yellow oil.Rf= 0.63 (methylene chloride); (22.2 g; 103 mmol; 85%)
