Triethylamine → N-{1-[2-(2-Amino-4-methylpyrimidin-5-yl)-9-(cyclopropylmethyl)-6-morpholin-4-yl-9H-purin-8-yl]pyrrolidin-3-yl}-N-methylmethanesulfonamide

Reaction Conditions

Reaction Steps

N-Methylpyrrolidone (1 ml) was added to 5-[8-chloro-9-(cyclopropylmethyl)-6-morpholin-4-yl-9H-purin-2-yl]-4-methylpyrimidin-2-amine (100 mg, 0.25 mmol) and 3-methylaminopyrrolidine (130 mg, 1.5 mmol) and the resulting mixture was stirred at 120° C. for 0.5 hours. The reaction mixture was partitioned with chloroform and saturated brine and the organic layer was washed with saturated brine and dried over magnesium sulfate. The solvent was concentrated under reduced pressure, triethylamine (100 μl, 0.75 mmol) and mesyl chloride (60 μl, 0.75 mmol) were added to the residue, and the resulting mixture was stirred for 1 hour. The reaction mixture was partitioned with ethyl acetate (containing a small amount of tetrahydrofuran) and water and the organic layer was washed with saturated brine and dried over magnesium sulfate. The solvent was evaporated under reduced pressure and then the residue was purified by silica gel chromatography (chloroform:methanol=9:1) to give a pale yellow solid (75 mg, 50%).
