Reaction Steps

Prepared according to procedure L. A mixture of 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (474 mg, 3.1 mmol) and 1,4-diazabicyclo[2.2.2]octane (694 mg, 6.2 mmol) in anhydrous DMSO (4.5 mL) was stirred at rt for 5 h and then added via cannula to a mixture of 1-(2-(2-chlorophenyl)-8-methylquinolin-3-yl)but-3-en-1-ol (500 mg, 1.5 mmol) and sodium hydride, 60% dispersion in mineral oil (180 mg, 4.5 mmol) in DMSO (3 mL) that had been stirred for 30 min at rt and 30 min at 50° C. prior to the addition. The mixture was stirred at rt for 6 h before addition of water (10 mL), and the mixture was extracted with EtOAc (4×20 mL). The combined organic layers were washed with water, brine, dried (MgSO4) and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: DCM/MeOH, 50/1) to provide 3-(1-(7H-pyrrolo[2,3-d]pyrimidin-4-yloxy)but-3-enyl)-2-(2-chlorophenyl)-8-methyl-quinoline [PI3Kδ IC50=28 nM] as a white solid. 1H-NMR (CDCl3) δ 10.20 (s, br, 1H), 8.22 (d, J=7.5 Hz, 1H), 7.15-7.64 (m, 8H), 6.59-6.62 (m, 1H), 6.34-6.37 (m, 1H), 5.64-5.79 (m, 1H), 4.93-5.01 (m, 2H), 2.74 (t, J=8.7 Hz, 2H), 2.70 (s, 3H). Mass Spectrum (ESI) m/e=441 (M+1).
