실험 절차

Triethylamine (2 mL 14 mmol) was added to a DCM (50 mL) solution containing chloroacetyl chloride (1 mL, 14 mmol) and compound 391 (3 g, 14 mmol). The resulting mixture was stirred 2 h at 23° C. The solvent was stripped and THF was added followed by potassium tert-butoxide (5 g, 41 mmol). The resulting solution was stirred overnight at room temperature. The reaction was then concentrated to dryness and the resulting residue was washed with 200 mL of absolute ethanol. The ethanolic solution was then concentrated to give 3.16 g of 9-(phenylmethyl)-4-oxa-1,9-diazaspiro[5.5]undecan-2-one. The material was used in the next step without further purification. LCMS-ESI (POS), M/Z, M+1: Found 261, Calculated 261.
