Trifluoroacetic acid → HCID 67261286, compound

Participants

Reaction Steps

To a solution of the product from Step 2 (200 mg, 0.39 mmol) in dichloromethane (1.5 mL) was added trifluoroacetic acid (0.49 mL). The mixture was stirred for 1 h at room temperature and then concentrated under reduced pressure. The resulting residue was taken up in dichloromethane and washed with saturated aqueous sodium bicarbonate. The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure to afford 1-[5-(3-{[4-(azetidin-3-yloxy)pyrimidin-2-yl]amino}-5-methylphenyl)-1,3-thiazol-2-yl]cyclobutanol (158 mg, 0.39 mmol, 98%) as a pale-yellow foam.
