Reaction Steps

2,6-dichloronicotinonitrile (0.500 g, 2.89 mmol), (4-fluorophenyl)methanamine (0.816 mL, 0.904 g, 7.23 mmol), and triethylamine (1.21 mL, 0.877 g, 8.67 mmol) were all mixed in NMP (10 mL). The resulting solution then was heated at 50° C. for 18 hr. The reaction mixture was then poured in H2O (25 mL), and extracted with EtOAc (3×25 mL). The combined extracts were washed with H20 (4×25 mL), and brine (1×25 mL). The organic layer was separated and dried (Na2SO4), filtered, and the solvent removed in vacuo. The resulting residue was purified using silica gel column chromatography. Elution using 1 EtOAc/3 hexanes to 3 EtOAc/1 hexanes afforded 0.6024 g (80%) of 6-chloro-2-(3-fluorobenzylamino)nicotinonitrile. LCMS (m/z): 350.0 (MH+), retention time=0.96 min. 1H NMR (300 MHz, CDCl3) δ 4.58 (d, J=5.86 Hz, 2 H) 5.48 (br. s., 1 H) 6.30 (d, J=8.50 Hz, 1 H) 6.96-7.06 (m, 2 H) 7.10 (d, J=7.62 Hz, 1 H) 7.28-7.38 (m, 1 H) 7.58 (d, J=8.79 Hz, 1 H).
