반응 단계
(4-Acetamidophenyeboronic acid {670 mg, 3.7 mmol), Nickel (II) iodide (35 mg, 0.11 mmol), trans-2-aminocyclohexanol (17 mg, 0.11 mmol), and Sodium hexamethyldisilazane (690 mg, 3.7 mmol) were weighed into a microwave reaction vial. A septum was placed over the top, nitrogen was purged and Isopropyl alcohol (5.7 ml, 75 mmol) was added. The vial was purged with nitrogen for 10 minutes and 3-iodooxetane (344 mg, 1.87 mmol) was added in 0.75 ml isopropyl alcohol. The septum was replaced with a microwave vial cap and the mixture was heated in a microwave reactor (microwave conditions: CEM Discovery Explorer microwave reactor; Ramp time: 10 min; 80° C. for 30 min; power: 300 W). The crude reaction mixture was diluted with 8 ml EtOH and the suspension was filtered through a pad of solka Floc®. The pad was washed with 35 ml EtOH and the filtrate was concentrated. The crude material was purified by flash chromatography (SiO2, eluting with 40-60% EtOAc/CH2Cl2) to give the desired product as an oil (200 mg).
