Reaction Steps

A mixture of 4-(3-Phenyl-pyrazin-2-yl)-piperidine-1-carboxylic acid tert-butyl ester (89) (128 mg, 0.38 mmol) in 4 M HCl/MeOH solution (10 mL) was stirred at RT. for 30 min. Then the solvent was evaporated at 40° C. to give 2-phenyl-3-piperidin-4-yl-pyrazine hydrochloride (90) (105 mg, 0.38 mmol, 100% yield) as a yellow solid.
