반응 단계
29.04 g of a catalyst mixture of 2-aminopyridine/dibutyl tin dilaurate (molar ratio 1:1) in 37 ml of toluene are reacted with 4.76 g of phenyl isocyanate at room temperature. Petroleum ether is added to the resulting suspension after 11/2 hours and the colorless precipitate is suction filtered. 7 g of N-(2-pyridyl)-N'-phenyl urea, m.p. 186°-188° C. are isolated.
