Diclofensine (Ro 8-4650) was developed by

abuse potential.[12][13]

Diclofensine is chemically a tetrahydroisoquinoline (THIQ) derivative, as is nomifensine.

Synthesis

Patents:[14][15] Also:[16]

The condensation of m-anisaldehyde [591-31-1] (1) with methylamine gives N-methyl-3-methoxybenzenemethanimine [16928-30-6]. Reduction of this Schiff-base intermediate with sodium borohydride gives (3-methoxybenzyl)methylamine [41789-95-1] (2). Alkylation of this with 3,4-dichlorophenacylbromide [2632-10-2] (3) would give CID:59580342 (4). Reduction of the benzoyl ketone with sodium borohydride gives the alcohol [802051-24-7] (5). Acid catalyzed intramolecular cyclization then completes the synthesis of the 4-aryl-THIQ derivative, diclofensine (6).
