(40 mL). The reaction mixture was heated at reflux in
a Dean–Stark
apparatus. Cyclohexenone (0.59 mL, 6.0 mmol) was further added after 4 h.
After 8 h, the reaction mixture was cooled to room temperature, washed with
satd NaHCO3 (30 mL), water (30 mL) and brine (30 mL), dried over MgSO4 and
then filtered and concentrated. The resulting oil was subjected to silica gel
flash column chromatography (ethyl acetate/hexane 8:2). Recrystallisation of
the solid from hot ethyl acetate gave 1.48 g of 1a as a yellow solid (32%).
