| [General Description]
1-Methylindole-2-carboxylic acid reacts with thionyl chloride to yield sulfinyl chlorides. | [Synthesis]
The general procedure for the synthesis of 1-methylindole-2-carboxylic acid from methyl 1-methyl-1H-indole-2-carboxylate was as follows: to a mixed solution of THF/H2O (2:1, 15 mL) of methyl 1-methyl-1H-indole-2-carboxylate (250 mg, 1.32 mmol) at 23 °C, LiOH-H2O (291 mg, 6.94 mmol). The reaction mixture was stirred at room temperature overnight. Upon completion of the reaction, the mixture was concentrated under reduced pressure to remove the solvent and subsequently partitioned between H2O (100 mL) and ether (100 mL). The aqueous layer was adjusted to pH 2-3 with 1.0 N HCl and then extracted with ethyl acetate (2 x 100 mL). The organic layers were combined, dried over anhydrous MgSO4, filtered and concentrated to give 1-methyl-1H-indole-2-carboxylic acid (210 mg, 91% yield). | [References]
