Sodium Iodide → 2-Nitro-6-(2-oxoethyl)benzoic Acid Methyl Ester

Participants

Reaction Steps

To a solution of 2-(2-methoxy-vinyl)-6-nitro-benzoic acid methyl ester (Step A, 3.33 g, 14.1 mmol, 1.0 eq) and CH3CN (20 mL) was added NaI (2.3 g, 15.5 mmol, 1.1 eq) and TMSCl (2 mL, 15.5 mmol, 1.1 eq). The reaction was stirred at RT for 4 h, then quenched with saturated NH4Cl and extracted with EtOAc. The organic layer was washed with H2O and brine, dried (MgSO4) and concentrated in vacuo to give a red-orange oil. Purification by silica flash chromatography (0-30% EtOAc:hexane) gave the desired compound as an orange oil.
