온도90 °C

반응 단계

A solution of N-phenylglycine (Fluka) (30.2 g, 0.2 moles) in 900 ml of water and 1 ml of acetic acid was heated to 60° C. After thirty minutes potassium cyanate (16.2 g, 0.2 moles) in 100 ml of water was added. Heating was continued for 90', then 25 ml of 37% hydrochloric acid were added and the reaction mixture was heated for 15 h at 90° C. After cooling the precipitate was filtered and crystallized from 95% ethanol. 8.65 g of 1-phenylhydantoin were obtained, m.p. 197°-198°.
