Versuchsvorschrift

The product of Example 157 (42.5 mg., 0.0001 mol) stirring at 23° in dry THF (5 mL), under Ar, was treated with ethyl isocyanate (9.6 mg, 0.0001 mol) in one portion. After 30 min., the resulting red solution was stripped to dryness; taken up in methylene chloride (5 mL) and applied to a Chromatotron™ Rotor Plate (1000 u thickness); plate eluted with methylene chloride-methanol gradient (0% to 2% MeOH), to afford 30 mg (60.4%) of pure title compound. (m.p. 130°-133°). LC MS (m/e)=497 (MH+). Rt=2.04 min.

Aufarbeitung

  1. washplate eluted with methylene chloride-methanol gradient (0% to 2% MeOH)
