Preparation of Radioactive Organic Compounds, II. L-3-Methoxy[3H]-ωM-[1-hydroxy-1-phenyl-isopropylamino]-propiophenone Hydrochloride2)3H-Methyliodide (1) is used for the methylation of m-methoxy[3H]-acetophenone (2). The resulting radiochemically pure m-methoxy[3H]-acetophenone (3) with formaldehyde and 1-norephedrine (4) gives the title compound 5. Following the course of this Mannich reaction by thinlayer chromatography and radiometric measurements, it is shown that 3 cannot be transformed completely into 5.
Notizen:
Methyljodid-[3H] (1) wird im Überschuß zur Methylierung von m-Hydroxy-acetophenon (2) eingesetzt. Das erhaltene, radiochemisch reine m-Methoxy-[3H]-acetophenon (3) gibt mit Formaldehyd und 1-Norephedrin (4) die Titelverbindung 5.
