참여 물질

반응 단계

To a 350 milliliter glass pressure bottle equipped with a magnetic stirrer was added 4.54 grams (0.020 moles) of 4-(2-hydroxybenzylideneamino)-3-methylphenol prepared in Part A, 2.57 grams (0.045 moles) of methyl isocyanate, 100 milliliters of ethyl acetate and 5 drops of dibutyltin diacetate. The resulting reaction mixture was stirred for 24 hours at room temperature forming a precipitate. The precipitate was removed from the reaction mixture by filtration, washed with cold hexane and air dried to give 5.69 grams (0.020 moles) of 4-(2-hydroxybenzylideneamino)-3-methylphenyl methylcarbamate in the form of a yellow solid having a melting point of 156.5°-157° C. and the following structural formula: ##STR7##
