実験手順

The resultant compound of Example 70 (769 mg, 1.04 mmol) was combined with 3-(chloromethyl)benzoyl chloride (3.95 mg. 2.09 mmol) and pyridine (165 mg, 2.09 mmol) in 10 mL of freshly distilled methylene chloride. The reaction mixture was stirred at ambient temperature under nitrogen for approximately 65 h and then diluted with 150 mL of chloroform. The chloroform solution was washed with 75 mL of water, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue (1.59 g) was taken up in ~10 mL of methylene chloride and applied to a 1.5×45 cm column of 40 mesh silica gel. The column was eluted @~5 p.s.i. sequentially with 200 mL of methylene chloride, 200 mL of 0.5% methanol in methylene chloride and 200 mL of 1% methanol in methylene chloride to give 275 mg (30% yield) of the title compound, FAB MS M/Z: 889 (M+H)+. The 300 MHz 1H NMR spectrum was consistent with the assigned structure.
