Procedure
Beginning with 5.4 gm (15.3 mMol) 1-benzyl-3-ethyl-4-hydroxy-4-(6-fluorobenzofur-7-yl)piperidine, 5.91 gm (88%) 1-benzyl-3-ethyl-4-(methyl oxoacetoxy)-4-(6-fluorobenzofur-7-yl)piperidine was recovered as an orange oil, essentially as described in EXAMPLE 16. This material was treated with tri(n-butyl)tin hydride essentially as described in EXAMPLE 16 to provide 4.91 gm of the desired compound.
