Reaction Steps

The title compound was prepared from 2'-methyl-4'-(5-methyl-1,3,4-oxadiazol-2-yl)biphenyl-4-carboxylic acid (D11) and 2,3,5,6,7,8-hexahydro-1'-methylspiro[furo[2,3-g]quinoline-3,4'-piperidine] (D10) using a similar procedure to Example 1 as a white solid (62%). This was converted to its oxalate salt which was obtained as a white solid (mp 187-188° C.) and hydrochloride salt (mp 176-180° C.).
