실험 절차

Sodium hydride (36 mg, 0.91 mmol) was added to a mixture of 3-bromo-1-chloro-5-(1-chloroethyl)-4-methoxy-2-methylbenzene (150 mg, 0.503 mmol), 3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (110 mg, 0.76 mmol) in N,N-dimethylformamide (8 mL) and the reaction was stirred at 30° C. overnight. The mixture was diluted with methylene chloride, washed with sat. NaHCO3, water, brine, dried over Na2SO4, filtered and concentrated. The crude product was purified by silica gel chromatography, eluting with 0 to 70% EtOAc in CH2Cl2 (103 mg, 50%). LCMS calculated for C16H18BrClN5O (M+H)+: m/z=410.0; Found: 410. The racemic products were applied on a Phenomenex Lux-Cellulose 1 column (21.1×250 mm, 5 micron particle size), eluting with 5% ethanol in hexanes at a flow rate of 18 mL/min, ˜13 mg/injection, to provide two enantiomers.
