Procedure

A mixture of 150 mg (0.43 mmole) of 4-aminomethyl-3-{4-chloro-2-[(2-fluorophenyl)hydroxymethyl]phenyl}-2-methyl-1H-pyrrole and 600 mg (7.3 mmole) of manganese dioxide in 30 ml of tetrahydrofuran was refluxed for 2 hours. The mixture was cooled and filtered over celite. The filtrate was concentrated at reduced pressure to give an amber oil. Purification by column chromatography (silica gel, 10 g; eluent 5% ether in methylene chloride) gave a cream colored solid. Recrystallization from ether gave colorless needles, mp 226°-227° which was identical in every respect to an authentic sample.
