HCID 98928961'-Methyl-5-(2'-methyl-4'-(5-methyl-1,3,4-oxadiazol-2-yl)biphenyl-4-carbonyl)-2,3,6,7-tetrahydrospiro[furo[2,3-f]indole-3,4'-piperidine]

Procedure

The title compound was prepared from 1'-methyl-2,3,6,7-tetrahydrospiro[furo[2,3-f]indole-3,4'-piperidine] (D8) and 2'-methyl-4'-(5-methyl-1,3,4-oxadiazol-2-yl)biphenyl-4-carboxylic acid (D11) using a procedure similar to that of Example 1 (23%). This was converted to the oxalate salt which precipitated from acetone/ether as a white solid (mp 232-235° C.), and hydrochloride salt (mp>250° C.).

Workup

  1. customprecipitated from acetone/ether as a white solid (mp 232-235° C.), and hydrochloride salt (mp>250° C.)
