When the residue liquid reaches a volume of 50 cc., boiling acetonitrile (200 cc.) is added. After cooling for 2 hours at 2° C., the crystals which have appeared are filtered off, washed three times with ice-cold acetonitrile (total 15 cc.) and dried under reduced pressure (20 mm. Hg). The crystals thus isolated (8.0 g.) are dissolved in boiling acetonitrile (270 cc.), decolourising charcoal (0.2 g.) is added to the boiling solution and the whole is filtered. After 24 hours at 2° C., the crystals which have appeared are filtered off, washed three times with ice-cold acetonitrile (total 10 cc.) and dried under reduced pressure (20 mm. Hg). 5-(4-Methylpiperazin-1-yl)carbonyloxy-6-(1,8-naphthyridin-2-yl)-7-oxo-2,3,6,7-tetrahydro-1,4-dithiino[2,3-c]pyrrole (5.8 g.), melting at 255° C., is thus obtained.

DMF (1 ml) and sodium thiomethoxide (12.4 mg, 0.18 mmol) were added and the reaction mixture was heated in microwave reactor at 150° C. Sodium thiomethoxide was added after 30, 30 and 20 min of heating (12.4 mg, 5.6 mg and 5.6 mg, respectively). After total of 90 min of heating DMF was evaporated, and the evaporation residual was taken up in DCM and washed with water. Organic phase was dried over Na2SO4, filtered and evaporated. Thus obtained crude product was suspended in MeCN. Suspension was filtered to give 9 mg (14%) of the title compound as a colourless solid. Filtrate was purified by CombiFlash (column: C-18 silica, eluent: 0-100% MeCN in water) to yield 13 mg (20%) of the title compound. 1H-NMR (400 MHz; d6-DMSO): δ 1.11-1.20 (m, 3H), 2.49 (s, 3H, overlap with DMSO) 2.57-2.64 (m, 3H), 4.20-4.55 (m, 3H), 6.91 (s, 1H), 7.31 (s, 1H), 7.62-7.89 (m, 4H), 8.47 (dd, 1H), 14.2 (d, 1H).
