1-(3-溴-5-氯-2-甲氧基苯基)乙胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 1-(3-bromo-5-chloro-2-methoxyphenyl)ethanamine (2.2 g, 8.5 mmol) in ethanol (69 mL), was treated with 6-bromo-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (3.6 g, 13 mmol, from Example 108, Step 1) and N,N-diisopropylethylamine (4.4 mL, 25 mmol) and heated at reflux overnight. The reaction mixture was cooled, poured into sodium bicarbonate (150 mL) and extracted with ethyl acetate (2×150 mL). The combined organic layers were washed with water and brine, dried with sodium sulfate, filtered, and concentrated to a crude residue. Purification by flash column chromatography using acetonitrile in dichloromethane (5%-10%) and then ethyl acetate in hexanes (60%-100%) gave the desired product (3.9 g, 98%). LCMS for C19H22BrClN5O2 (M+H)+: m/z=466.1, 468.1. Found: 466.0, 468.0. heated at reflux overnight The reaction mixture was cooled extracted with ethyl acetate (2×150 mL) The combined organic layers were washed with water and brine dried with sodium sulfate filtered concentrated to a crude residue Purification by flash column chromatography
