反応手順

A suspension of propane-2,2-diyldibenzene (3.93 g, 20 mmol) and 1-aza-tricyclo[3.3.1.1*3,7*]decane (2.80 g, 20 mmol) in TFA (35 mL) was heated at 100° C. for 16 h. The reaction mixture was allowed to cool to RT, poured onto cold water and made alkaline (pH=9) with solid K2CO3. The aqueous solution was extracted with Et2O (3×250 mL) and the separated organics were dried over Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, petroleum ether:EtOAc 95:5) affording the title compound (3.47 g, 15.46 mmol).
