Reaktionsschritte
47 g (0.376 mol) of p-fluorobenzylamine, 30.4 g (0.353 mol) of furan-2-one and 0.4 g of hydroquinone are introduced into a 125 ml autoclave. After driving the air out of the apparatus by passing a stream of nitrogen through it, the mixture is heated to 250° for 6 hours. It is then cooled and distilled under reduced pressure. 51 g (yield = 74.8%) of 1-p-fluorobenzyl-pyrrolidin-2-one are collected as a colourless liquid distilling at 103°-105° under a pressure of 0.01 mm of mercury and solidifying slowly. Melting point = 37°-38°.
