Participants

Reaction Steps

The compound of Example 56 (150 mg) and triethylamine (0.5 mL) were dissolved in 10 mL of acetonitrile, and 0.1 g of propionyl chloride was added dropwise to the mixture and the mixture was stirred at room temperature for 30 minutes. After removing the solvent, the residue was dissolved in chloroform. Thereto water was added, the organic layer was washed with water (twice), then brine (once), and dried over magnesium sulfate. After the solvent was removed under reduced pressure, the resulting oil was purified by chromatography on silica gel (methylene chloride-methanol-aqueous ammonia=90:10:1) to give 50 mg of N-[4-(6-amino-5-cyano-2-{6-[3-(4-methylpiperazin-1-yl)-3-oxopropyl]pyridin-2-ylmethylsulfanyl}pyrimidin-4-yl)phenyl]propionamide as a light yellow powder.
