Hydrochloric Acid → HCID 70003226, compound

Participants

Reaction Steps

2 g (7.48 mmol) of Nε-(4-nitrophenyl)-L-lysine are dissolved in 30 ml of ethanol, 9 ml of water and 5.2 ml (3.5 eq) of 5N hydrochloric acid in a 250 ml glass reactor (Paar apparatus). 2 g of palladium-on-charcoal with a moisture content of 50% and an active content of 10% are then introduced. The mixture is hydrogenated under a pressure of approximately 2.76×105 Pa for 1 hour and at a temperature of 10° C. After filtering through celite, the filtrate is evaporated. The purplish oily residue is taken up in ethanol and precipitated from a large volume of acetone with stirring. After filtration, 2.6 g of a white crystalline powder are obtained, i.e. a final yield of 99%.
