Procedure

Following a procedure similar to that described in Example 3(a), but using 0.23 g of 2-[1-(4-biphenylyl)-ethylideneaminooxy]ethanol (prepared as described in Preparation 15), 0.40 g of 5-(4-hydroxybenzyl)-3-trityloxazolidine-2,4-dione, 0.40 g of tributylphosphine and 0.50 g of 1,1'-(azodicarbonyl)dipiperazine, 0.31 g of the title compound was obtained as a crystalline powder, melting at 193°-195° C.
