実験手順

To a 2 mL microwave vial was added 2-(4-(4-((6-chloropyridazin-3-yl)sulfonyl)piperazin-1-yl)phenyl)-1,1,1,3,3,3-hexafluoropropan-2-ol (50 mg, 0.099 mmol), EtOH (1.0 mL) and ammonium hydroxide (2.0 mL, 51 mmol). The solution was heated in an Emrys Optimizer microwave reactor (Personal Chemistry, Biotage AB, Inc., Uppsala, Sweden) at 110° C. for 1 h and then concentrated. The resulting material was purified by silica gel chromatography (0 to 4% MeOH in CH2Cl2) to afford 2-(4-(4-((6-aminopyridazin-3-yl)sulfonyl)piperazin-1-yl)phenyl)-1,1,1,3,3,3-hexafluoro-2-propanol (29 mg) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ 8.40 (s, 1H), 7.67 (d, J=9.4 Hz, 1H), 7.47 (d, J=8.6 Hz, 2H), 7.28 (s, 2H), 7.02 (d, J=9.0 Hz, 2H), 6.89 (d, J=9.2 Hz, 1H), 3.29-3.33 (m, 4H), 3.22-3.28 (m, 4H). m/z (ESI, +ve ion) 485.9 (M+H)+. GK-GKRP IC50 (Binding)=0.285 μM; GK-GKRP EC50 (LC MS/MS-2)=0.302 μM.
