Reaction Steps

A 8-mL vial was charged with methyl 2-[[4-[[2-(5-chloro-2-thienyl)-5-ethyl-6-methyl-pyrimidin-4-yl]amino]phenyl]methyl]-1H-imidazole-4-carboxylate (8 mg, 0.017 mmol, 1 eq.), LiOH/H2O (19 mg, 0.44 mmol, 26 eq.), THF (1 ml), MeOH (0.2 ml) and water (0.2 ml). The resulting mixture was stirred at 55° C. overnight. After cooling to room temperature, the mixture was added 2N HCl aq. to pH 6˜7. The precipitate was collected by filtration and washed with water. After drying, the title compound was obtained as a solid (4.8 mg, 62% yield). MW=453.94. 1H NMR (400 MHz, DMSO-d6) δ 8.52 (brs, 1H), 7.65 (m, 3H), 7.55 (d, J=4.0 Hz, 1H), 7.25 (d, J=8.0 Hz, 2H), 7.16 (d, J=4.0 Hz, 1H), 3.97 (s, 2H), 2.73 (q, J=7.2 Hz, 2H), 2.49 (s, 3H), 1.09 (t, J=7.2 Hz, 3H).
