Procedure

Compound (Da), 3-methyl-4-[(1S,4S)-5-methyl-2,5-diazabicyclo[2.2.1]heptan-2-yl]aniline, (0.105 g, 0.6 mmol) and 1-(tert-butoxycarbonylamino(tert-butoxycarbonylimino)methyl)pyrazole (H) (0.186 g, 0.6 mmol) were combined in DMF (2 mL) and stirred at ambient temperature for 3 days. The reaction was monitored by LCMS. The homogenous reaction mixture was then diluted with water (20 mL), the solid precipitate formed was isolated by filtration, and purified by column chromatography (silica gel, CH2Cl2 then 2-5% MeOH in CH2Cl2) to give [3-methyl-4-((1S,4S)-2-methyl-2,5-diazabicyclo[2.2.1]heptan-5-yl)phenyl][N,N-bis(tert-butoxycarbonyl)]guanidine; LCMS: purity: 99%; MS (m/e): 460 (MH+).
