Procedure
The method of operation is the same as that used for the synthesis of the compound of Example 1 (coupling with 1-ethoxy-1-(trimethylstannyl)ethylene), 6-bromo-3-benzyloxazolo[4,5-b]pyridin-2(3H)-one from Preparation 13 being used instead of 6-bromo-3-methyloxazolo[4,5-b]pyridin-2(3H)-one. The yield obtained is 75%. ##STR47##
