実験手順

A mixture of 26.56 g (0.1579 mol) of 2-(N-acetylamino)-4-amino-1-fluorobenzene, 35.89 ml (0.1776 mol) of diethyl ethoxymethylenemalonate, and 30 ml of toluene is stirred at 130° C. for 3 hours. After cooling, the precipitate which forms is triturated with ether to yield 50.64 g (94.8%) of title compound as a white solid:
