“…Finally, we found that alcoholysis of the bromoketone 9 with methanol at 54 °C over several days gives 1 in 64% yield while in refluxing methanol we obtained significantly lower yields of 1. The spectroscopic data of the synthetic product are in accordance with those published for the natural product [5].…”
