Reaction Steps

The title compound was prepared from 4'-(5-dimethylamino-1,2,4-oxadiazol-3-yl)-2'-methylbiphenyl-4-carboxylic acid D(14) 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 (26%). This was converted to hydrochloride salt. M.p. 118-120° C.
