실험 절차
Into a suitable agitated reactor is charged 4-fluorophenylacetic acid (79.4 kg, 515 mol), N,N-dimethylformamide (0.5 kg, 6.8 mol), and toluene (318 kg). Oxalyl chloride (68.3 kg, 538 mol) is added at a rate as to maintain the temperature below 35° C. The solution is stirred for at least 7 hours at about 25° C., typically affording a 22.1 wt % solution of 4-fluorophenylacetyl chloride.1
