Dimethylformamide → HCID 59244837, compound

Participants

Reaction Steps

To a dimethylformamide solution (1 ml) of 4-(3-t-butoxyphenyl)-2-morpholin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidine (11 mg), sodium hydride (60% mineral oil dispersion, 1.5 mg, 1.2 equivalents) was added with ice cooling, followed by stirring at room temperature for 30 minutes. With ice cooling, tosyl chloride (6.6 mg, 1.1 equivalents) was added, followed by stirring at room temperature for 10 hours. To the reaction mixture, water (5 ml) was added, followed by extraction with ethyl acetate (5 ml×2). The organic layer was washed with aqueous ammonium chloride solution and brine, followed by drying 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 (11 mg, 70%).
