실험 절차

A mixture of 5-bromo-6-chloro-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 12.2, 1 g, 2.53 mmol) and (3R,4S)-pyrrolidine-3,4-diol (313 mg, 3.03 mmol) in a mixture of DIPEA (0.883 mL, 5.06 mmol) and iPrOH (2.53 mL) was subjected to MW irradiation at 140° C. for 30 min. The RM was treated with 0.5 M aq. HCl (30 mL) and extracted with EtOAc. The combined extracts were washed with sat. NaHCO3, brine and dried over Na2SO4. The crude product was purified by flash chromatography (RediSep® Silica gel column, 40 g, cyclohexane/EtOAc, from 50% to 100% EtOAc) to yield the title compound as a white amorphous solid. UPLC-MS (Condition 3) tR=0.98 min, m/z=462.1-464.0 [M+H]+, m/z=460.1-462.0 [M−H]−; 1H-NMR (400 MHz, DMSO-d6) δ ppm 3.61 (dd, J=11.13, 4.28 Hz, 2H) 3.84 (dd, J=10.76, 4.89 Hz, 2H) 4.10 (d, J=3.42 Hz, 2H) 4.96 (d, J=3.91 Hz, 2H) 7.35 (d, J=8.80 Hz, 2H) 7.85 (d, J=8.80 Hz, 2H) 8.34 (s, 1H) 8.67 (s, 1H) 10.21 (s, 1H).
