Reaktionsschritte
2.1 4.8 ml of triethylamine are added dropwise to a solution of 11.0 g of 2-hydroxycyclohexanone and 9.6 g of malononitrile in 25 ml of methanol, and the mixture is stirred at room temperature for a further 4 hours. The crystals which deposit are separated off and washed with methanol, giving 12.8 g of 2-amino-4,5,6,7-tetrahydrobenzofuran-3-carbonitrile (“BA”), m.p. 179°.
