3-[(3aR,5S,7aS)-5-Methyltetrahydro-1H-pyrano[3,4-c][1,2]oxazol-7a(7H)-yl]benzonitrile → 3-[(3S,4R,6S)-3-amino-4-(hydroxymethyl)-6-methyltetrahydro-2H-pyran-3-yl]benzonitrile

Participants

Reaction Steps

3-[(3aR,5S,7aS)-5-Methyltetrahydro-1H-pyrano[3,4-c][1,2]oxazol-7a(7H)-yl]benzonitrile (C21) was converted to the product using the method described for the synthesis of 3-[(3S,4R,6S)-3-amino-4-(hydroxymethyl)-6-methyltetrahydro-2H-pyran-3-yl]-4-chlorobenzonitrile (C18) in Example 6. The resulting product was used in the next step without further purification. Yield: 105 mg, 0.426 mmol, 60%. LCMS m/z 247.1 [M+H+].
