To a suspension of 2,3,9,10-tetrachloro-6,13-pentacenequinone (1.0 g, 2.24 mmol) in dry MeOH (40 mL) at 0° C. under an argon atmosphere was slowly added NaBH4 (0.85 g, 22.47 mmol). The reaction mixture was stirred at 0° C. for 0.5 h and at RT for 16 h, and then quenched with H2O at 0° C. The resulting mixture was filtered and washed with H2O and dried in vacuo to give product as a brown solids (0.92 g, 90%) which was identified as mixture of two isomers. 1H NMR (500 MHz, DMSO-d6): δ 8.36 (s, 4H), 8.16 (s, 4H), 6.82 (d, 2H), 5.82 (d, 2H). 1H NMR (500 MHz, DMSO-d6): δ 8.35 (s, 4H), 8.13 (s, 4H), 6.30 (d, 2H), 5.99 (d, 2H). LDI-MS m/z: 449.96[M+], 431[M+-OH], 415.97 [M+-2(OH)].
