Acetyl chloride → HCID 58094900, compound

Participants

Reaction Steps

To a mixture of 7-[5-(1-allyl-1H-imidazol-2-yl)-4-(2,4-dichlorophenyl)-2-thienyl][1,3]thiazolo[5,4-d]pyrimidin-2-amine (200 mg, 0.41 mmol) and pyridine (20 mL), was added acetyl chloride (0.30 mL, 4.2 mmol) at rt. After being stirred for 1 hour, acetyl chloride (0.30 mL, 4.2 mmol) was added at rt. After being stirred for 2 hours, the mixture was concentrated in vacuo. To the residue, were added sat. NaHCO3 and EtOAc. After being stirred for 30 min, the organic layer was washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. The residue was washed with ether to yield the title compound (204 mg, 90%) as a pale yellow solid. LCMS: (AA) ES+527, 529. 1H NMR (400 MHz, d6-DMSO) δ: 12.76 (s, 1H), 8.97 (s, 1H), 8.68 (s, 1H), 7.77 (d, J=2.3 Hz, 1H), 7.44 (dd, J=8.3, 2.3 Hz, 1H), 7.26-7.23 (m, 2H), 7.04 (d, J=1.3 Hz, 1H), 5.70-5.62 (m, 1H), 5.09-5.06 (m, 1H), 4.85-4.80 (m, 1H), 4.38 (d, J=5.3 Hz, 2H), 2.25 (s, 3H).
