Reaktionsschritte

A mixture of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (1 g, 4.5 mmole), 1-bromo-2-methoxyethane (0.7 g, 5 mmole) and K2CO3 (1.3 g, 9 mmole) in DMF (10 mL) was heated at 85° C. for 20 hr, diluted by ethyl acetate, washed by water, dried over MgSO4, filtered, concentrated under vacuum, purified by ISCO (silica gel, elute: 10% ethyl acetate in hexane) to give liquid product (316 mg, 25% yield). MS (ESI) m/z: Calc. 278.2 (M+). Found: 279.3 (M++1).
