Benzoyl chloride → HCID 18700031, compound

Participants

Reaction Steps

585 mg (2.0 mmol) of the free form compound obtained in Example 8 was dissolved in 20 ml of methylene chloride, 0.6 ml (4.0 mmol) of triethylamine, 0.28 ml (2.4 mmol) of benzoyl chloride and 4-DMAP (cat.) were added, and the mixture was stirred at room temperature for 19 hours. The reaction solution was washed with water and then dried over anhydrous magnesium sulfate. The solvent was evaporated, and the resulting residue was subjected to a silica gel column chromatography, which was eluted with chloroform-methanol (80:1) to give 510 mg of the title compound in its free form. Using 140 mg (1.2 mmol) of fumaric acid, a 490 mg (1.24 mmol) portion of this compound was subjected to salt formation to give 348 mg of the title compound.
