Reaction Steps

(2-Oxo-propyl)-[5-(2-m-tolylamino-pyrimidin-4-yl)-thiophen-2-yl]-carbamic acid tert-butyl ester (0.078 mmol) was treated with 1 mL 4N HCl in dioxane. After 1½ hours, the mixture was concentrated in vacuo and redissolved in EtOAc. The organics were washed with saturated NaHCO3, dried over Na2SO4 and concentrated. The residue was purified by prep LCMS to afford title compound (2.8 mg, 10.5% yield for 2 steps). %). MS: m/z 339 (M+H+). 1H NMR (500 MHz, DMSO-d6) δ2.15 (s, 3H), 2.318 (s, 3H), 4.077 (d, J=5.5 Hz, 2H), 5.94 (d, J=4 Hz, 1H), 6.73 (d, J=8 Hz, 1H), 7.02 (d, J=5.5 Hz, 1H), 7.13 (t, J=8 Hz, 1H), 7.41 (t, J=6 Hz, 1H), 7.52 (br d, J=9 Hz, 1H), 7.59 (d, J=4 Hz, 1H), 7.75 (br s, 1H), 8.19 (d, J=5.5 Hz, 1H), 9.27 (s, 1H).
