Reaction Steps

To a suspension of 2-(2,6-difluorophenyl)-1,3-thiazole-4-carboxylic acid (28.5 mg, 0.118 mmol) in DCM (0.5 mL), a solution of 1-chloro-N,N,2-trimethylpropenylamine (45.0 mg, 0.337 mmol) in DCM (1.0 mL) was added slowly. The mixture was stirred at room temperature for 2 h. A solution of tert-butyl [(3S)-1-(3-aminoquinolin-4-yl)piperidin-3-yl]carbamate (from step 2 in Example 1, 36.9 mg, 0.108 mmol) in DCM (2.0 mL) was added, followed by pyridine (93.2 mg, 1.18 mmol). The mixture was then stirred at room temperature for a further 2 h, and then concentrated under reduced pressure. The resulting residue was purified by chromatography on silica gel (0-100% EtOAc in hexanes) to give the title compound as a pale yellow oil (57.4 mg, 94%). LCMS calc. for C29H30F2N5O3S (M+H)+: m/z=566.2. found 566.2.
