Hydrochloric Acid → Cinacalcet Hydrochloride

Participants

Reaction Steps

0.3 g of cinacalcet base was stirred in 6 ml of n-heptane at room temperature. Then, 3 ml of 1N HCl were added in one portion, resulting in an immediate precipitation. The resulting mixture was stirred at room temperature, i.e., about 20° to about 25° C., overnight. The product was isolated by filtration, washed with 4 ml of n-heptane, and dried at 50° C. in a vacuum oven for 25 hours, yielding 0.3 g of cinacalcet hydrochloride crystalline Form I.
