Versuchsvorschrift

Benzoyl choride (0.014 ml) was added to a solution of Intermediate 16 (0.04 g) and N,N-diisopropylethylamine (0.048 ml) in dichloromethane (3 ml). The solution was stirred for 5 h at 23° C. The solvent was removed in vacuo and the residue purified by solid phase extraction (Isolute SCX sulphonic acid column) eluting with methanol followed by 10% 0.880 ammonia solution in methanol. The basic fraction was concentrated in vacuo and the residue was further purified using a silica gel solid phase extraction cartridge (1 g Varian Bond Elut), eluting sequentially with dichloromethane, ethyl acetate, acetone, acetonitrile, and methanol, to give the title compound as a clear gum (0.024 g).
