Procedure

According to the general procedure using: 27 (60 mg, 0.174 mmol), bromoethane (114 mg, 1.05 mmol), K2CO3 (241 mg, 1.74 mmol) and n-Bu4NI (6.4 mg, 17 μmol) in acetone (4.0 mL) were heated at reflux for 18 h. Purification by PTLC using AcOEt:hexane=6:4 (v/v) as eluent gave 28h as a clear oil (39 mg, 60%).
