Methyl iodide → 3-Amino-2-methoxy-4-nitrobenzonitrile

Participants

Reaction Steps

To a stirring suspension of 11A (0.34 g, 1.86 mmol) and K2CO3 (0.283 g, 2.05 mmol) in DMF (3 mL) was added iodomethane (0.127 mL, 2.05 mmol). After the addition, the reaction mixture was stirred at rt for 16 h, then partitioned between H2O and CH2Cl2. The separated CH2Cl2 layer was washed with water, brine, dried (Na2SO4), filtered and concentrated under reduced pressure. The residue was chromatographed (silica gel) eluting with 5% to 40% EtOAc/hexane to yield the title compound (0.22 g) as a solid.
