Reaction Steps

A glass microwave reaction vessel was charged with (S)-6-chloro-N-((4-(trifluoromethyl)phenyl)(3-(trifluoromethyl)pyridin-2-yl)methyl)nicotinamide (50 mg, 0.109 mmol, example 135), DMF (1 mL), and 2 M diethylamine in THF (0.054 mL, 0.109 mmol). The reaction mixture was stirred and heated in a Biotage Initiator at 100° C. for 30 minutes. This was repeated at 150° C. for 30 minutes at a time until LC-MS indicated complete consumption of starting material. The reaction product was purified by reverse-phase preparative HPLC (Shimadzu) on a Phenomenex Gemini column (5 micron, C18, 110 Å, Axia, 100×30 mm) eluting at 45 mL/min with a linear gradient of 20% to 70% MeCN (0.1% TFA) in water (0.1% TFA) over 20 minutes. The desired fractions were poured into 10% Na2CO3 and extracted with DCM (3×5 mL). The combined DCM layers were washed with brine, dried over MgSO4, and concentrated in vacuo to give the title compound as a white solid. 1H NMR (CDCl3, 300 MHz) δ ppm 8.86 (d, J=3.8 Hz, 1H), 8.66 (d, J=2.2 Hz, 1H), 8.02 (d, J=7.9 Hz, 2H), 7.92 (dd, J=9.1, 2.5 Hz, 1H), 7.54 (s, 4H), 7.45 (dd, J=7.7, 4.4 Hz, 1H), 6.87 (d, J=7.9 Hz, 1H), 6.49 (d, J=9.2 Hz, 1H), 3.14 (s, 6H) MS (ESI pos. ion) m/z: 469.0 (M+H).
