反応手順
102 parts of phenylurea was suspended in 80 parts of acetonitrile, and 25.4 parts of an α-methylstyrene solution containing 30.5% of cumyl chloride was added. With stirring, they were reacted at 40° C. for 5 hours. After allowing the reaction product to stand for 2 days, the precipitated crystals were collected and recrystallized from hydrous alcohol to afford 7.6 parts of N-phenyl-N'-(α,α-dimethylbenzyl) urea (III: R=C6H5). The melting point of the crystals was 193 to 194° C.
