Reaction Steps

To a suspension of 6-chloro-3-[2-(4-methyl-piperazin-1-yl)-ethyl]-4,5-dihydro-3H-10-thia-2,3,7,9-tetraaza-cyclopenta[a]fluorene (150 mg, 0.39 mmol) and 4-amino-O-cresol (71 mg, 0.58 mmol) in isopropanol (5 mL) was added 4M HCl in dioxane (0.67 mL, 2.7 mmol). The reaction mixture was sealed in a microwave reaction vessel and it was placed in a microwave instrument at 160° C. for 10 min. After it was cooled to room temperature, solvents were evaporated and the residue was dissolved in MeOH/water/DMF and purified by prep. HPLC. After drying, the TFA salt was neutralized with saturated NaHCO3 and extracted with a mixture of CHCl3:isopropanol (v/v, 3:1). The organic phase was dried over Na2SO4 and concentrated to dryness. The desired product was obtained as a pale solid (174 mg, 95%). 1H-NMR (CD2Cl2-d2) δ 8.34 (s, 1H), 7.55 (s, 1H), 7.28 (m, 2H), 6.88 (b, 1H), 6.80 (m, 1H), 4.20 (t, 2H, J=6.2 Hz), 3.38 (t, 2H, J=8.3 Hz), 3.13 (t, 2H, J=8.4 Hz), 2.85 (t, 2H, J=6.2 Hz), 2.62-2.45 (b, 8H), 2.30 (s, 3H), 2.26 (s, 3H); LCMS RT=1.89 min; [M+H]+=476.2.
