Participants

Reaction Steps

A solution of 4′-(2-aminopyrimidin-5-yl)-5′-fluorobiphenyl-2-thiol (300 mg, 1.00 mmol), 2-chloropyrimidine (229 mg, 2.00 mmol), PPh3 (262 mg, 1.00 mmol) and TEA (0.38 mL) in DMF (10 mL) was stirred at 120° C. under a N2 atmosphere over-night. The reaction mixture was then cooled to rt, concentrated to dryness, and the residue subjected to FCC purification to give the title compound (170 mg, 45%). MS (ESI): mass calcd. for C20H14FN5S, 375.10; m/z found, 375.9 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ 8.66 (s, 2H), 8.56 (d, J=4.9, 2H), 7.79-7.73 (m, 1H), 7.63-7.56 (m, 2H), 7.55-7.48 (m, 2H), 7.33-7.24 (m, 2H), 7.21 (t, J=4.9, 1H), 6.23 (s, 2H).
