43. When mentioned, deactivated silica gel means that it was treated with 5 % triethy-
lamine in pentane and the column was eluted with the same solvent mixture until the
outflowing eluent was basic according to pH paper.
44. The NH ester was N-benzoylated in methylene chloride by reaction with benzoyl
chloride in the presence of triethylamine.
