1-Butanol → 5-Butoxy-2-nitrobenzoic acid methyl ester

Participants

Reaction Steps

Sodium hydride (302.4 mg) was added to a solution of 1-butanol (0.634 mL) in DMF (15 mL). The reaction mixture was stirred until there was no further evolution of CO2 and then 5-fluoro-2-nitrobenzoic acid methyl ester (1.15 g) was added and the mixture was stirred at room temperature overnight. The reaction was then mixed with ethyl acetate, washed with 10% sodium bicarbonate and 10% citric acid solution, dried over sodium sulfate and concentrated. The crude product was purified by preparative HPLC. The product with the molecular weight of 253.26 (C12H15NO5) was obtained in this way; MS (ESI): 254 (M+H+).
