Vorschrift

Intermediate (4) (80 mg, 140 μmole, 1.0 eq) was dissolved in acetonitrile (10 mL) and phenyl isocyanate (18 μL, 168 μmole, 1.2 eq) was added. The mixture was refluxed for 24 hours, then diluted with water and extracted repeatedly with dichloromethane. Reconstituted in dichloromethane, filtered off precipitate and purified material isolated from filtrate by RP-HPLC to give title compound. 1H NMR (400 MHz, MeOH-d4): δ 0-75-9.0 (m, 4H), 1.38-1.60 (m, 2H), 1.68-1.84 (m, 4H), 3.21 (d, 2H, J=8 Hz), 3.86 (d, 2H, J=8 Hz), 4.51 (s, 2H), 7.0 (t, 1H, J=8 Hz) 7.17-7.30 (mult, 5H), 7.33-7.7.45 (mult, 4H), 8.11 (s, 1H), 8.42 (s, 2H).
