Reaction Steps
A solution of 2-bromo-5H-pyrrolo[2,3-b]pyrazine (531 mg, 2.68 mmol) and 4-benzyloxy-1-methyl-cyclohexanecarbonyl chloride (2.15 g, 8.05 mmol) in anhydrous Toluene (16 ml) was treated with Et2AlCl (1M in Hexanes, 5.36 ml, 5.36 mmol), dropwise. The reaction mixture was stirred at 90° C. for 16 hours. The reaction mixture was cooled to room temperature, quenched with sat. NaHCO3, and extracted with ethyl acetate (3×). The organic layers were collected, dried over MgSO4, filtered, and concentrated giving a dark brown oil. Silica gel chromatography using 0-50% Et2O in DCM as eluant provided 205 mg (18%) of (4-benzyloxy-1-methyl-cyclohexyl)-(2-bromo-5H-pyrrolo[2,3-b]pyrazin-7-yl)-methanone as a pale yellow solid. M−H=426.
