実験手順
A stirred mixture of 6-chloro-5-cyano-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 70.3, 4.50 g, 13.2 mmol), (R)-3-Pyrrolidinol (1.38 g, 15.8 mmol) and DIPEA (3.74 g, 29.0 mmol) in iPrOH (20 mL) was heated at 110° C. for 60 min. The cooled RM was then evaporated to dryness under reduced pressure and the residue was dissolved in EtOAc, washed with sat. aq. NaHCO3 and brine. The solution was dried over anhydrous Na2SO4 and the solvent was evaporated off under reduced pressure to give a crude product which was purified by crystallization from DCM/TBME to afford the product as a colorless crystalline solid. m.p. 234-236° C., HPLC (Condition 4) tR=5.41 min, UPLC-MS (Condition 8) tR=1.01 min, m/z=393.2 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 1.00-1.25 (m, 1H), 1.80-2.06 (m, 1H), 3.67 (d, J=11.34 Hz, 1H), 3.82 (br. s, 3H), 4.01 (q, J=7.04 Hz, 1H), 4.40 (br. s, 1H), 7.34 (d, J=8.60 Hz, 2H), 7.83 (d, J=8.99 Hz, 2H), 8.51 (d, J=2.35 Hz, 1H), 8.83 (d, J=2.35 Hz, 1H), 10.23 (s, 1H).
