Reaction Steps
12.4 parts of 2,4-xylylurea was suspended in 50 parts of acetonitrile, and 7.7 parts of cumyl chloride and 24 parts of α-methylstyrene were added. With stirring, they were reacted at 40° C. for 6 hours. After allowing the reaction mixture to stand for one day, 50 parts of n-hexane was added. The mixture was further allowed to stand overnight. The precipitated crystals were collected, and recrystallized from 60% methanol to afford 12.5 parts of N-(α,α-dimethylbenzyl)-N'-(2,4,urea (III: R=--C6H3 (CH3)2 --2,4) having a melting point of 163° C.
