実験手順

1.2 g (2.9 mmol) of the compound of Example 70, 0.31 g (2.9 mmol) of benzylamine and 0.2 ml (2.9 mmol) of acetic acid were dissolved in 50 ml of ethanol and, at room temperature, 0.18 g (2.9 mmol) of sodium cyanoborohydride was added a little at a time. The mixture was stirred for 16 h and then concentrated under reduced pressure, and the organic phase was dried and finally concentrated again under reduced pressure. The residue was purified by chromatography on silica gel (mobile phase: methylene chloride/methanol=5:1) to yield 0.87 g (60%) of the product.
