実験手順
Verapamil hydrochloride was added to a solution of 25% deuterated sulfuric acid in deuterated water (v/v) and deuterated methanol. The solution was stirred for 140 hours at 90° C. The pH was adjusted to 12.0 and the mixture extracted with ethyl acetate. The combined ethyl acetate extracts were washed with water, dried over magnesium sulfate and evaporated to yield a viscous oil. This oil was dissolved in ether and ethereal hydrochloride was added to precipitate the hydrochloride salt. The salt was collected by filtration and crystallized from ethyl acetate to obtain deuterated verapamil as a white solid.
