The alkylation of 2-(3,4-dimethoxyphenyl)-m-dithiane-1,1,3,3-tetraoxide (4) with N-(3-chloropropyl)-3,4-dimethoxy-N-methylphenethylamine (2) leads to N-(3,4-dimethoxyphenethyl)-2-(3,4-dimethoxyphenyl)-N-methyl-m-dithiane-2-propylamine-1,1,3,3-tetraoxide (5) (Ro 11-1781). The corresponding hydrochloride (5a), a new Ca++ antagonist, induces in the anaesthetized dog a substantial increase in myocardial flow. The preparation of two metabolites of 5a are described.

D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
