By condensation of trans-4-aminocyclohexanol (I) with 2-amino-3,5-dibromo-benzaldehyde (V) by means of formic acid at 200 C. When the condensation of the aminoalcohol (I) and the aldehyde (V) is performed with KOH in ethanol, the intermediate N-(2-amino-3,5-dibromobenzylidene)-trans-4-aminocyclohexanol (VI), m.p. 124.0-5.5 C is obtained, which is then reduced with NaBH4 in ethanol.
