Methanol → HCID 86201264, compound

Participants

Reaction Steps

To a mixture of the compound (117 mg) obtained in Example 417a, tetrahydrofuran (5 ml) and methanol (2 ml), lithium borohydride (10.7 mg) was added. The reaction mixture was stirred at room temperature for 15 h, and, after addition of water, concentrated under reduced pressure. To the resulting residue, 2 N HCl was added and the mixture was subjected to extraction with ethyl acetate. The organic layer was washed with a saturated aqueous sodium chloride solution, dried with anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent, ethyl acetate:n-hexane=1:2) to give the titled compound quantitatively.
