To 690 parts of a solution of aziridine in water 0.875M are added 42 parts of sodium hydrogen carbonate while cooling in an ice-salt bath at -5° C. While stirring vigorously, there is added dropwise, during a 30 minutes period, a solution of 78.8 parts of 2-hydroxybenzoyl chloride in 150 parts of trichloromethane at a temperature below 5° C. The reaction mixture is allowed to reach 25° C while stirring, and a diluted sodium hydroxide solution is added to pH 8. The product is extracted three times with trichloromethane. The combined extracts are washed three times with water, dried, filtered and evaporated, yielding 56 parts of 1-(2-hydroxybenzoyl)aziridine as a residue.
