Procedure: Prepared analogously to Example 27 from 2-(2-carbethoxy-ethyl)-cyclohexan-1,3-dione and 2-hydroxy-ethylamine.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 21.2 g (0.1 mol) of 2-(2-carbethoxy-ethyl)-cyclohexan- 1,3-dione and 200 ml of 24% ethanolic ethylamine solution are heated to 180° C. in a stirred autoclave for 3 hours. The reaction solution is evaporated down using a rotary evaporator and the residue is chromatographed on a silica gel column with cyclohexane/ethyl acetate (1:1).
