Versuchsvorschrift
To a round bottomed flask was loaded 1.1 grams of (3,4-Dihydro-2H-1-thia-4a,9-diaza-fluoren-6-yl)-methanol, 6 grams of manganese dioxide and 250 ml chloroform. The mixture was stirred for one hour at room temperature and then filtered through a pad of celite. This yielded 0.67 grams of product (61%). MS: 219.0 (M+H). H-NMR (CDCl3): δ 10.04 (s, 1H), 7.67 (m, 3H), 4.25 (m, 2H), 3.27 (m, 2H), 2.50 (m, 2H).
