| Product | 1-Methyl-3-phenylurea | HCID 13880 | — |
Reaction Steps
1-Methyl-3-phenylurea was prepared by the dropwise addition of methylisocyanate (6 ml, 0.1 mole) over three hours to an ether solution (100 ml) containing aniline (9 ml, 0.1 mole) at 4° C. with stirring. 1-Methyl-3-phenylurea precipitated as purple crystals which were recrystallized from ethanol, m.p. 150° C.
