Procedure

N1-(3-methyl-pyridin-2-yl)-N-(5,6,7,8-tetrahydro-quinolin-8-yl)-propane-1,3-diamine (63 mg, 0.20 mmol) and (tert-butoxycarbonylimino-pyrazol-1-yl-methyl)carbamic acid tert-butyl ester (110 mg, 0.31 mmol) was stirred in THF (0.3 mL) for 16 hours. The solvent was removed under reduced pressure, CH2Cl2 (10 mL) was added and the organic phase washed with 15% aqueous NaOH solution (5×5 mL). The organic phase was then dried (Na2SO4) and concentrated under reduced pressure to afford, after column chromatography with silica gel (33:1:0.1 CH2Cl2/MeOH:NH4OH), ({3-[(3-methyl-pyridin-2-ylmethyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amino]-propyl}-tert-butoxycarbonylimino-methyl)-carbamic acid tert butyl ester as a pale brown sticky solid (50 mg, 49%),
