Reaction Steps

Prepared according to Procedure H using (1S)-1-(7-fluoro-2-(thiophen-2-yl)-quinolin-3-yl)ethanamine (0.078 g, 0.286 mmol), 6-chloropurine (0.053 g, 0.344 mmol, 1.2 eq) and DIEA (0.58 mmol, 2.0 eq) in n-butanol (3 mL). N-((S)-1-(7-fluoro-2-(thiophen-2-yl)quinolin-3-yl)ethyl)-9H-purin-6-amine [PI3Kδ IC50=8 nM] was obtained after purification as a white solid. 1H-NMR (MeOD) δ ppm 8.62 (s, 1H), 8.43 (s, 1H), 8.37 (s, 1H), 8.00-8.07 (m, 1H), 7.62-7.73 (m, 3 H), 7.43-7.51 (m, 1H), 7.18 (m 1H), 1.78 (d, J=7.04 Hz, 3H), 1H), Mass Spectrum (ESI) m/e=391 (M+1).
