실험 절차

To a solution of tert-butyl (6S)-4′-chloro-6′-oxo-5,6′,7,7′-tetrahydrospiro[cyclopenta[b]pyridine-6,5′-pyrrolo[2,3-d]pyrimidine]-3-carboxylate (200 mg, 0.537 mmol) in dry ethyl acetate (5.37 mL) was added triethylamine (299 μL, 2.15 mmol) and palladium on carbon (571 mg, 10%, 0.537 mmol). The reaction was placed on a Parr apparatus at 50 psi hydrogen gas. After 16 h, the reaction mixture was filtered under a nitrogen atmosphere through Celite®, washing with ethyl acetate. The filtrate was concentrated to give the title compound, along with one equivalent of triethylamine hydrochloride. MS: m/z=339.3 (M+1).
