Participants

Reaction Steps

The title compound was prepared by the method described in Example 1, except that (i) commercially available 5-bromo-4-methyl-2-phenylthiazole (Apollo Scientific) was used instead of 5-bromo-2-phenylpyrimidine in Step C, and (ii) 3-(1-benzyl-1H-imidazol-2-yl)pyridine was used instead of 1-benzyl-2-phenyl-1H-imidazole in Step C. 3-(1-Benzyl-1H-imidazol-2-yl)pyridine was prepared by the procedure described in Example 8, Steps A and B except the commercially available 3-cyanopyridine was used instead of 3-fluorobenzonitrile; Rf 0.34 with 95:5 v/v dichloromethane-methanol; 1H-NMR (400 MHz; DMSO-d6) δ 8.87 (dd, 1H), 8.64-8.63 (dd, 1H), 7.94-7.91 (m, 1H), 7.86-7.84 (m, 2H), 7.43-7.22 (m, 8H), 6.83-6.81 (m, 2H), 5.25 (s, 2H), 2.31 (s, 3H); MS (ESI+) m/z 409.1 (M+1); H-PGDS FPBA IC50: >20 μM.
