Sulfinalol is a beta adrenergic receptor antagonist.

Synthesis

The methyl group on a sulfoxide is sufficiently acidic to substitute for phenolic hydroxyl.

Sulfinalol synthesis: R. E. Philion, (1978 to Sterling), C.A. 90, 137468 (1979).

The preparation of this combined α- and β-blocker sulfinalol begins by protection of the phenolic hydroxyl as its benzoate ester. Bromination followed by condensation with 4-(4-methoxyphenyl)butan-2-amine (not PMA) gives the aminoketone 3. Successive catalytic reduction and saponification affords aminoalcohol 4. Oxidation of the sulfide to the sulfoxide with a reagent such as metaperiodate gives sulfinalol (5).
