Participants

Reaction Steps

Under argon, 138 mg (0.256 mmol) of the compound from Example 22A were initially charged in 3 ml of acetaldehyde, a spatula tip of 4-toluenesulfonic acid monohydrate was added and the mixture was stirred at RT for 1 h. 2.5 ml of methanol were then added to the reaction solution, and after 2 h the mixture was concentrated and the residue was purified by column chromatography (silica gel, toluene/acetonitrile 2:1→1:1).
