1.14 g of 3,5-dichloroaniline (10 mmol), 0.97 g of glyoxylic acid hydrate (15 mmol) and 1.40 g of cyclopentadiene (freshly distilled) (30 mmol) were dissolved in 20 ml of acetonitrile in a closable Teflon vessel and heated to 50° C. within one minute in a microwave oven with a power of 800 watts and kept at this temperature for five minutes with further microwave irradiation. The vessel was then placed in ice water, cautiously opened and evaporated in a rotary evaporator. The mass of crystals obtained was washed with hexane and dried. A colourless mass of crystals was obtained in a quantity of 1.95 g (98% of theoretical).
