Reaction Steps

1′-{[1-(4-Hydroxyphenyl)cyclopropyl]-carbonyl}-3H-spiro[furo[3,4-c]pyridine-1,3′-pyrrolidin]-3-one (8.2 mg, 0.023 mmol), triethylamine (3.6 ul, 0.026 mmol), triphenylphosphine (15 mg, 0.056 mmol), and diisopropyl azodicarboxylate (11 ul, 0.056 mmol) were mixed in tetrahydrofuran (0.2 ml) at room temperature for 10 minutes. To the mixture, with stirring, was added (1-methylcyclopropyl)methanol (4.8 mg, 0.056 mmol). The resulting mixture then was stirred at room temperature overnight. The desired product was obtained from the mixture by prep-HPLC (5.8 mg, 59%). LCMS: m/z 419.1 (M+H)+.
