反応手順

200 mg (0.598 mmol) of the compound from example 43A were initially charged in ethanol (10 ml), then 144 mg (1.20 mmol) of 2,3-dihydroxy-1,4-dioxane were added and the reaction mixture was stirred at RT for 5 h. The solid formed was filtered off, washed with ethanol and dried under high vacuum. This gave 90 mg (41% of theory) of the title compound in solid form.
