実験手順

200 mg of phenethyl bromide was added to a mixture solution of 350 mg of the Compound (1) obtained in the Example 1 and 172 mg of triethylamine in 5 ml of acetonitrile, and the mixture was stirred for 5 hours at 60° C. Then, 5 ml of saturated ammonium chloride solution was added to the reaction mixture and the mixture was extracted with ethyl acetate. The extract was washed with brine, dried and concentrated under reduced pressure to give a residue. The obtained residue was purified by amine-coated silica gel (Fuji Silysia Chemical Ltd.; NH-DM1020) column chromatography (methylene chloride:methanol=20:1) to give 390 mg (83%) of the above-mentioned compound (28).
