Reaction Conditions

Reaction Steps

To a 48 mL pressure tube containing a stirbar were added 2-chloropyrimidine (1.69 g, 14.7 mmol), 2-bromophenol (1.63 mL, 14.0 mmol), Cs2CO3 (5.49 g, 16.8 mmol) and DMSO (30 mL). The vial was sealed and heated at 120° Celsius for 15 hours. The reaction was then diluted with 100 mL of ethyl acetate and extracted with brine (2×50 mL). The organic layer was isolated, dried and concentrated to dryness to provide the crude product which was subsequently purified FCC to provide the title compound. 1H NMR (500 MHz, CDCl3) δ 8.57 (s, 1H), 8.56 (s, 1H), 7.72-7.60 (dd, J=8.0, 1.6, 1H), 7.45-7.34 (m, 1H), 7.32-7.23 (m, 1H), 7.23-7.11 (m, 1H), 7.10-7.01 (t, J=4.8, 1H).
