Participants

Reaction Steps

A solution of indane 2-carboxylic acid (324 mg, 2 mmol) and carbonyldiimidazole (299 mg, 2.2 mmol) in DMF (5 mL) was stirred at room temperature for 30 min. N,N-diisopropylethylamine (0.522 mL, 3 mmol) was added followed by N-methoxymethyl amine hydrochloride (195 mg, 2 mmol). The reaction mixture was stirred at room temperature for 18 h, and then treated with 1N sulfuric acid (100 mL). The mixture was extracted with methylene chloride (3×50 mL), and the combined extracts were washed with water, dried over anhydrous sodium sulfate, and evaporated to give N-methoxy-N-methyl-indane-2-carboxamide as a light brownish oil which was used without further purification in the next step.
