Participants

Reaction Steps

A dimethyl sulfoxide solution (1.0 ml) of 5-[8-chloro-9-(cyclopropylmethyl)-6-morpholin-4-yl-9H-purin-2-yl]-N-methylpyrimidin-2-amine (103.3 mg, 0.21 mmol) and morpholine (74.3 mg, 0.85 mmol) was heated at 140° C. and stirred for 3 hours. Morpholine (74.3 mg, 0.85 mmol) was added, the resulting mixture was further stirred for 3 hours, left standing to cool followed by the addition of dichloromethane-methanol (10:1), and the resulting mixture was washed with saturated aqueous sodium hydrogen carbonate solution. The organic layer was dried over anhydrous sodium sulfate, the mixture was filtrated, the filtrate was concentrated under reduced pressure, and the resulting residue was purified by preparative thin layer silica gel chromatography (dichloromethane:methanol=10:1) to give the title compound (87.1 mg, 91%) as a pale yellow solid.
