Reaction Steps

The title compound was prepared from 4'-(5-ethyl-1,3,4-oxadiazol-2-yl)-2'-methylbiphenyl-4-carboxylic acid (D32) and 2,3,5,6,7,8-hexahydro-1'-methylspiro[furo[2,3-g]quinoline-3,4'-piperidine] (D10) using a procedure similar to that of Example 1 (19%). This was converted to its hydrochloride salt, as a white solid. M.p. 241-3° C.
