Versuchsvorschrift

A mixture of 2.0 g of 4,5,6,7-tetrahydro-3H-imidazo[4,5-c]pyridine dihydrochloride, 2.36 g of NaHCO3 and 2.45 g of N-(benzyloxycarbonyloxy)succinimide in 80 ml of dioxane/water mixture (50/50; v/v) is stirred for 16 hours at RT. The reaction mixture is extracted with EtOAc, the organic phase is washed with a saturated solution of NaHCO3, with a 0.1 M solution of HCl, with saturated NaCl solution, it is dried over Na2SO4 and the solvent is evaporated under vacuum. The residue is purified by silica gel chromatography, eluting with DCM/MeOH mixture. 1.9 g of the expected compound is obtained.
