Reaction Steps

A mixture of {(5S)-5-[(6-nitrothieno[3,2-b]pyridin-7-yl)amino]-5,6-dihydro-2H-pyran-2-yl}methyl acetate (366 mg, 1.05 mmol) and 10% palladium on carbon (0.18 g) in methanol (7.0 mL) was subjected to balloon pressure of H2 at room temperature for 2 h. The mixture was filtered and treated with 1 M NaOH (1 mL) for 1 h. The mixture was diluted with methanol and purified with prep-LCMS (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 60 mL/min) to give two peaks in 5:1 ratio. The major peak is the title compound (154 mg, 58%). LCMS calculated for C13H18N3O2S (M+H)+: m/z=280.1. Found: 280.1.
