Versuchsvorschrift

The intermediate 3-(4-bromophenyl)-1-methyl-3-oxo-1-propenamine, m.p. 126°-128° C., 56.8 g, was prepared following the procedure described in Example A-2 using 83 g of 1-(4-bromophenyl)-1,3-butanedione, 750 ml of methanol and 100 ml of concentrated aqueous ammonium hydroxide solution. The solid residue after stripping the reaction mixture to dryness on a rotary evaporator was treated with 500 ml of boiling n-hexane, the mixture allowed to stand at room temperature overnight, and, the product collected and dried at room temperature.
