Procedure
Beginning with 1.24 gm (3.48 mMol) 1-benzyl-3-methyl-4-hydroxy-4-(4,6-difluorobenzofur-7-yl)piperidine, 1-benzyl-3-methyl-4-(methyl oxoacetoxy)-4-(4,6-difluorobenzofur-7-yl)piperidine were prepared essentially as described in EXAMPLE 16. This material was treated with tri(n-butyl)tin hydride essentially as described in EXAMPLE 16 to prepare 0.91 gm (77%) of the desired compound.
