Pyridine → HCID 59244687, compound

Participants

Reaction Steps

To an acetonitrile solution (2 ml) of 4-(3-t-butoxyphenyl)-2-morpholin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidine (36 mg), an acetonitrile solution (1 ml) of pyridine (25 μl, 3 equivalents), dimethylaminopyridine (ca. 2 mg, catalytic amount) and benzoyl chloride (28 mg, 2 equivalents) was added under ice cooling, followed by stirring at room temperature for 10 hours. To the reaction mixture, water (20 ml) was added, followed by extraction with ethyl acetate (10 ml×2). The organic layer was washed with aqueous ammonium chloride solution and brine, and subsequently dried over sodium sulfate. After filtering off the drying agent, the filtrate was concentrated under reduced pressure, and the resulting residue was purified by preparative TLC (n-hexane/ethyl acetate=2/1), to obtain the desired compound as a colorless powder (42 mg, 90%).
