Trans-N,N&#8217;-dimethylcyclohexanediamine (154 mu^, 0.98 mmol) was added and the reaction heated to 150 C for 18 h using microwave irradiation. The mixture was partitioned between EtOAc and water. The aqueous layer was then extracted with EtOAc (3 x). The combined organic layers were washed with brine, dried (MgS04), filtered and evaporated in vacuo. The residue was purified by FCC, using 0- 100% EtOAc in cyclohexane, to give the title compound (307 mg, 24%).
