실험 절차

(rac)-{1-[3-(7-Fluoro-quinolin-6-ylmethyl)-imidazo[1,2-b]pyridazin-6-yl]-pyrrolidin-3-yl}-methyl-carbamic acid tert-butyl ester (Stage 260.1, 179 mg, 0.376 mmol) was dissolved in DCM (7.5 mL) and TFA (3 mL). The RM was stirred at rt for 1 h. A basic work up (1 M Na2CO3) followed by a crystallization in Et2O afforded the title compound as white crystals (tR 2.28 min (conditions 13), MH+=377, 1H-NMR in DMSO-d6: 8.83 (m, 1H); 8.30 (d, 1H); 7.93 (d, 1H); 7.75 (m, 2H); 7.48 (dd, 1H); 7.35 (s, 1H); 6.74 (d, 1H); 4.37 (s, 2H); 3.52-3.35 (m, 3H); 3.23-3.17 (m, 2H); 2.27 (s, 3H); 2.07 (m, 1H); 1.86 (bs, 1H); 1.80 (m, 1H)).
