Procedure
A mixture of N-((S)-1-(8-chloro-2-(pyridin-2-yl)quinolin-3-yl)ethyl)-9H-purin-6-amine (80 mg, 0.2 mmol), Pd(PPh3)4 (23 mg, 0.1 eq) and Zn(CN)2 (117 mg, 5.0 eq) in DMF (5 mL) was purged with N2 for 5 min before heating to 130° C. After 3 h, LCMS showed formation of trace amount of 2. The reaction was then heated to 165° C. over night. After cool to rt, the reaction was filtered through Celite™ and purified by reverse HPLC (MeCN/H2O, 0.1% TFA) to give a white solid. 1H-NMR (400 Hz, DMSO-d6) δ 8.83 (s, 1H), 8.72 (s, 1H), 8.52 (s, 1H), 8.42-8.37 (m, 3H), 8.14 (d, J=8.0 Hz, 1H), 8.08 (t, J=8.0 Hz, 1H), 7.79 (t, J=8.0 Hz, 1H), 7.55 (t, J=8.0 Hz, 1H), 6.24 (s, 1H), 1.72 (d, J=8.0 Hz, 3H). Mass Spectrum (ESI) m/e=393 (M+1).
