A mixture of 1-acetyl-6-amino-4-phenyl-1,2,3,4-tetrahydro-2,2,4-trimethylquinoline (10 mg), phenyl isocyanate (8.0 mg) and N,N-diisopropylethylamine (22 l) in tetrahydrofuran (1 ml) was stirred for 18 h. The reaction mixture was concentrated in vacuo, the residue was dissolved in ethyl acetate and washed with 0.5 M HCl, water, 5% aq. NaHCO3, water and brine. The organic layer was dried (MgSO4) and concentrated in vacuo. The residue was chromatographed on silicagel in heptane/ethyl acetate=1/0=>0/1 (v/v) as eluent.
