実験手順
Ethyl acetate saturated with gaseous HCl was added to a solution of 1-(tert-butoxycarbonyl)-4-(6-chloro-pyrimidin-4-yl)piperazine (16.80 g) in ethyl acetate (50 ml) and the resulting suspension stirred at ambient temperature for 3 hours. Solvent was evaporated to give (6-chloro-pyrimidin-4-yl)piperazine hydrochloride (13.25 g) as a cream solid.
