Procedure

p-Toluenesulfonic acid monohydrate (1.6 mg, 0.0084 mmol) is added to a stirred solution of 3,5-diamino-6-chloro-pyrazine-2-carboxylic acid [8-{1-[2-(tetrahydro-pyran-2-yloxy)-ethyl]-1H-indole-4-carbonyl}-1,3,8-triaza-spiro[4.5]dec-(2E)-ylidene]-amide (Ex. 84) (50 mg, 0.084 mmol) in MeOH (3 ml) and the resulting solution is stirred at room temperature for 3 hrs, then heated at 50° C. for 16 hours. The solvent is removed in vacuo and the residue is dissolved in MeOH (3 ml) and loaded onto a 1 g PEAX cartridge which is eluted with MeOH (20 ml). The filtrate is concentrated in vacuo to afford the title compound; [M+H]+ 512/514
