実験手順
To a round bottomed flask was loaded 1.16 grams of (3,4-Dihydro-2H-1-thia-4a,9-diaza-fluoren-6-yl)-methanol, 25 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 0.42 grams of product (42%). MS: 203.0 (M+H). H-NMR(CDCl3): δ 10.10(ss, 1H), 8.24(ss, 1H), 7.85 (m, 3H), 6.96 (m, 1H).
