To phenylboronic acid (5 g, 41.0 mmol) in DCM (50 mL) was added copper (II) acetate (0.78 g, 4.1 mmol) and the mixture was stirred for 5 min at room temperature. 2-Methoxyethanamine (3.08 g, 41.0 mmol) was added and the mixture was stirred at 40 C for 19 h. The mixture was then passed through a silica plug and then purified by FCC, eluting with 10% EtOAc in heptane to afford the title compound (1.065 g, 17% yield). Method B HPLC-MS: MH+ requires m/z=152 Found: m/z=152, Rt=1.08 min (87%).
