Participants

Reaction Steps

A solution of 2-methoxy-aniline (37 mg) in dry dichloromethane (3 ml) was treated with triethylamine (0.04 ml) followed by 20% phosgene in toluene (0.08 ml). The mixture was stirred at room temperature for 1 h, and then Intermediate 3 (37 mg) was then added, and the stirring continued for 18 h. The mixture was partitioned between water and ethyl acetate. The organic layer was passed through a hydrophobic frit and evaporated and the residue was purified on a silica gel SPE cartridge. Gradient elution with 0-5% methanol in dichloromethane gave the title compound as a colourless solid (24 mg).
