Hydrochloric Acid → Cinacalcet Hydrochloride

Participants

Reaction Steps

A solution of cinacalcet base was formed by dissolving 1.0 g of cinacalcet base in 4 ml of absolute ethanol. Then, 15 ml of 1N hydrochloric acid (“HCl”) was added drop-wise to the solution. The resulting mixture was stirred at ambient temperature for 20 hours, producing a precipitate. The product was isolated by filtration, washed with 6 ml of water, and dried in a vacuum oven at 50° C. for 24 hours, yielding 0.97 g of cinacalcet hydrochloride. The final product was analyzed by powder XRD. The resulting powder XRD diffractogram illustrated in FIG. 2, shows the product to be cinacalcet hydrochloride crystalline Form I.
