Reaction Conditions

Temperature110 °C

Reaction Steps

900 mg (S)-histidinol (×2HCl) are dissolved in 20 mL HBr in acetic acid (32%) and heated to 110° C. in the microwave for 6 h. The solvent is eliminated in vacuo, the residue is dissolved in ethanol and again freed from the solvent in vacuo. This crude product is used in the next reaction step without further purification.
