実験手順

Ethyl 1-chlorocarbonylcyclopropanecarboxylate (3.11 grams, 0.02 mole), prepared in Example XVIII, 4-bromo-N-methylaniline (3.00 grams, 0.02 mole) and triethylamine (1.63 grams, 0.02 mole) were reacted in a manner similar to that described in Example III to give 3.79 grams (0.01 mole) of ethyl 1-[N-(4-bromophenyl)-N-methylaminocarbonyl]cyclopropanecarboxylate isolated as a colorless oil.
