The benz[g]isatin was prepared in two steps from 5,6,7,8-tetrahydro-1-naphthylamine using the methods described for 1,6,7,8-tetrahydrocyclopenta[g]indole-2,3-dione (G. W. Rewcastle et. al., J. Med. Chem., 1991, 34, 217). The product (54% yield from N-[1-(5,6,7,8-tetrahydronaphthalenyl)]-2-(hydroximino)acetamnide) was obtained as an orange solid: mp. 234-235° C. (lit. [U.S. Pat. No. 1,856,210, 1929] 232° C.); NMR δH (400 MHz; DMSO-d6) 1.73 (4H, m), 2.49 (2H, m), 2.73 (2H, m), 6.78 (1H, d, J 7.7 Hz), 7.21 (1H, d, J 7.7 Hz) and 10.92 (1H, s).
