Iodoethane → 2-(2-Benzyloxypyridin-3-yl)-4-tert-butyl-5-methoxybenzoic acid ethyl ester

Participants

Reaction Steps

step 1—To a solution of 76 (100 mg, 0.26 mmol) in DMF (3 mL) were added Cs2CO3 (101 mg, 0.31 mmol) and iodoethane (25 μL, 0.31 mmol). The reaction mixture was stirred at RT overnight then quenched with H2O and thrice extracted with EtOAc. The combined organics were washed with H2O (3×), dried (MgSO4), filtered and concentrated under reduced pressure to afford 109 mg (99%) of 2-(2-benzyloxypyridin-3-yl)-4-tert-butyl-5-methoxybenzoic acid ethyl ester (78) as a pale yellow foam.
