Sodium Chloride → HCID 20186089, compound

Participants

Reaction Steps

479 Milligrams of 2-(4-chlorobenzoylamino)-3-(oxindol-3-yl)propionic acid 1/4-hydrate prepared in Example 3 and 0.05 g of sodium amide were admixed in 5 ml of dimethylformamide, and the mixture was stirred at a room temperature for 2 hours. Then 0.17 g of allyl chloride was added to the mixture and the resulting reaction mixture was stirred at a room temperature for 10 hours. The reaction mixture was poured into 13 ml of a saturated sodium chloride aqueous solution, and the organic material was extracted with chloroform. The chloroform layer was washed with water, dried, then chloroform was removed by evaporation. The residure thus obtained was purified by means of a silica gel column chromatography to yield 85 mg of 2-(4-chlorobenzoylamino)-3-(1-allyloxyindol-3-yl)propionic acid.
