Reaction Steps
The title compound was prepared from 4'-acetamido-2'-methylbiphenyl-4-carboxylic acid (D13) and 1'-methyl-2,3,6,7-tetrahydrospiro[furo[2,3-f]indole-3,4'-piperidinel (D7) using oxalyl chloride to give the title compound as a yellow oil (43%). This was converted to its oxalate salt which crystallised as a white solid from acetone.
