반응 단계
Following the procedure described in Example 1, 611 g of 2,4-diaminotoluene, 480 g of urea, 178 g of ethyl carbamate and 1590 g of ethanol (approximately 96%) were reacted for 6.5 hours at 200° C. in the pressure apparatus described in Example 1. After cooling and venting of the apparatus, the reaction mixture was removed, filtered and analyzed by liquid chromatography (HPLC). A yield of 881 g (66% of the theoretical yield) of 2,4-bis-(ethoxy carbonyl amino)-toluene was determined.
