実験手順

To a magnetically stirred solution of 0.138 g (0.25 mmol) of the product of Step A in 1.0 mL ethanol was added 0.5 mL of a 5.0N solution of sodium hydroxide and the reaction was stirred at room temperature overnight. The reaction mixture was adjusted to pH=6 with 1.0N hydrochloric acid and then concentrated in vacuo. The residue was then purified on a silica gel flash chromatography column eluted with CHCl3 --MeOH--NH4OH (80:15:1). Evaporation of the purified fractions and drying in vacuo afforded 0.103 g (79%) of the title compound.
