実験手順

A solution of (E)-3-{1′-tert-butoxycarbonyl-4-oxo-spiro[chromane-2,4′-piperidine]-6-yl}-acrylic acid (387 mg, 1 mmol) in DCM (15 ml) was cooled down to 0° C. EDC (383 mg, 2 mmol) and HOBT (135 mg, 1 mmol) were added, and the mixture was stirred at RT for 1 h. NH2OTHP (146 mg, 1.25 mmol) in DCM (1 ml) was added dropwise and the mixture was stirred at RT. After 4 h, the reaction mixture was washed with a saturated NaHCO3 solution and brine, dried over Na2SO4 and concentrated. The crude residue was purified by column chromatography (eluent: DCM/MeOH 98:2) to give (E)-3-{1′-tert-butoxycarbonyl-4-oxo-spiro[chromane-2,4′-piperidine]-6-yl}-N-(tetrahydro-pyran-2-yloxy)-acrylamide
