In a suitable apparatus (500 ml flask), 23.0 g (0.1 mol) of N-chloroacetyl-N-isopropyl-4-fluoroaniline and 11.7 g (0.11 mol) of sodium carbonate are refluxed (100° C.) in a solution of 140 ml of water and 200 ml of N-methylpyrrolidone. After 2.5 hours, the solvent mixture is stripped off in vacuo and the residue distilled at 2 to 3 torr and 132° to 135° C. This gives 18.1 g (86% of theory) of N-hydroxyacetyl-N-isopropyl-(4-fluoroaniline) with a purity of 99.1% (GC).
