Sodium Methoxide → HCID 67383505, compound

Participants

Reaction Steps

A solution of (S)-1-fluoro-3,7-di(pyridin-3-yl)-5′H-spiro[chromeno[2,3-c]pyridine-5,4′-oxazol]-2′-amine (40 mg, 0.094 mmol) and sodium methoxide (52.4 μL, 0.940 mmol) in 15 mL of MeOH was heated to 65° for 5 h. After cooling to rt, the reaction was evaporated to dryness and was partitioned between water (100 mL) and EtOAc (100 mL). The layers were separated and the organics were dried over sodium sulfate, filtered and evaporated to dryness. Flash column (CH2Cl2 to CH2Cl2/MeOH=100:5 to 100:10 to 100:20) gave (S)-1-methoxy-3,7-di(pyridin-3-yl)-5′H-spiro[chromeno[2,3-c]pyridine-5,4′-oxazol]-2′-amine as an off white solid.
