Potassium Carbonate → (E)-3-[3'-adamantan-1-yl-4'-(2-morpholin-4-yl-ethoxy)biphenyl-4-yl]-acrylic acid methyl ester

K2CO3 (265 mg, 1.92 mmol) was added to a solution of (E)-3-(3′-adamantan-1-yl-4′-hydroxybiphenyl-4-yl)-acrylic acid methyl ester (250 mg, 0.64 mmol) in DMF (2.5 ml) and the mixture was stirred at RT for 30 min. 4-(2-Chloroethyl)-morpholine hydrochloride (155 mg, 0.83 mmol) was added and the solution was heated to 60° C. for 14 h. The reaction was quenched by addition of water and was extracted with EtOAc. The organic layer was washed with a saturated solution of NaHCO3, water and brine, dried over Na2SO4 and evaporated under reduced pressure to obtain (E)-3-[3′-adamantan-1-yl-4′-(2-morpholin-4-yl-ethoxy)biphenyl-4-yl]-acrylic acid methyl ester (193 mg, 60%) after purification on silica gel (EtOAc:hexane 50:50).
