実験手順

4.9 is prepared analogously to the method according to II.1. Yield: 2.36 g (19% of theory) starting from 9.9 g (0.023 mol) of commercially obtainable isopropyl 4,4′-dibromobenzilate and 3.21 g (0.023 mol) of tropenol; to purify it, the hydrochloride was precipitated and recrystallized from acetonitrile. TLC: Rf value: 0.30 (eluant as in step II.1); melting point: 205° C.-207° C. (hydrochloride).
