반응 단계
Into a suitable reactor is charged 4-fluorophenylacetic acid (122.5 kg, 795 mol), N,N-dimethylformamide (0.37 kg, 5.1 mol), and toluene (490 kg). Oxalyl chloride (105.2 kg, 829 mol) is added at a rate to maintain the temperature at about 35° C. The solution is stirred for at least 7 hours at about 25° C., typically affording a solution of about 22.1 wt % 4-fluorophenylacetyl chloride (99% yield as determined by HPLC assay).
