Procedure

A mixture of (1R)-1′-{[1-(4-hydroxyphenyl)cyclopropyl]carbonyl}-3H-spiro[furo[3,4-c]pyridine-1,3′-pyrrolidin]-3-one (10 mg, 0.00003 mol), tetrahydro-4H-pyran-4-ol (6.5 μL, 0.000068 mol), diisopropyl azodicarboxylate (13 μL, 0.000068 mol), and triphenylphosphine (18 mg, 0.000068 mol) in tetrahydrofuran (200 μL, 0.002 mol) was stirred at room temperature overnight. It was purified with prep-HPLC to afford 2.3 mg of product. LCMS: m/z 435.1 (M+H)+.
