Reaction Steps

0.03 mol (6.16 g) of 2-hydroxy-4-aminophenoxyethanol hydrochloride is dissolved in 34 ml of water at 15° C. 0.03 mol (2.43 g) of potassium isocyanate dissolved in 7.5 ml of water is added to this solution, with stirring. The temperature of the reaction medium rises to 25° C. After stirring for 30 minutes, the expected product which has precipitated is filtered off. It is washed with a normal solution of hydrochloric acid and then with water. After recrystallization from acetic acid and drying in vacuo, the product melts at 191° C.
