実験手順

The product of the example was also prepared using the procedures of Method B as described in Example 21. 6-Iodo-1H-benzo[cd]indol-2-one (0.2 g, 0.68 mmol), benzylamine hydrochloride (0.195 g, 1.36 mmol) and p-toluenesulfonic acid monohydrate (0.01 g, 0.052 mmol) were stirred in hexamethyldisilazane (0.45 ml) for 3 h at 130°. Workup as before provided the crude product. Crystallization from EtOAc-ether gave 0.172 g (66%) of a dark yellow solid: mp 160-163°; NMR (CDCl3) δ 4.90 (s, 2H), 6.99 (d, J=7.3, 1H), 7.36 (m, 3H), 7.46 (m, 2H), 7.62 (m, 1H), 7.78 (m, 1H), 7.87 (m, 2H). MS (EI) m/z 385 (M+H calcd. for C18H14IN2 385).
