실험 절차

2-Chloro-N-(5-methoxy-2-methylphenyl)-acetamide (3 g), 3-chloro4-fluoroaniline (7.56 g), diisopropylethylamine (13.8 ml), potassium iodide (0.005 g) and anhydrous tetrahydrofuran (20 ml) were heated together at 105° C. in a sealed tube for 19 hours. The mixture was then cooled and concentrated. Purification of the residue by silica gel chromatography (eluting with 1:1 iso-hexane/ethyl acetate) gave the sub-title compound (3.93 g).
