実験手順

Tetrahydro-pyran-4-one (68 mg, 0.68 mmol) was added to a solution of the amine of example 4 (130 mg, 0.34 mmol) in dichloromethane (5 ml). The mixture was stirred at room temperature for 0.25 hours before sodium triacetoxyborohydride (217 mg, 1.0 mmol) was added, and the reaction mixture was stirred for a further 18 hours. Further tetrahydro-pyran-4-one (68 mg, 0.68 mmol) and sodium triacetoxyborohydride (217 mg, 1.0 mmol) were added and the reaction mixture was heated to 40° C. for 24 hours. The reaction mixture was partitioned between 2N aqueous sodium carbonate solution (10 ml) and ethyl acetate (50 ml). The organic layer was washed three times with 2N aqueous sodium carbonate solution (10 ml), once with saturated aqueous brine, and then dried over magnesium sulphate before filtering and evaporating the filtrate under reduced pressure. The residue was purified by chromatography on silica gel using a gradient of ethyl acetate in pentane (0% to 30%) as eluant, followed by chromatography on silica gel using a gradient of methanol in dichloromethane (0% to 5%) as eluant, to afford the title compound as a brown foam (80 mg).
