Reaction Steps

11.65 g (37.67 mmol) of the compound from Example 13A were initially charged in DMSO (37 ml). Subsequently, 2.42 g (41.44 mmol) of sodium chloride and water (7 ml) were added, and the mixture was stirred in a microwave at 150° C. for 30 min. The reaction mixture was diluted with ethyl acetate, and the organic phase was washed three times with water and once with saturated aqueous sodium chloride solution, dried over sodium sulphate, filtered and concentrated. This gave 9.07 g (89%, 85% of theory) of the desired compound in solid form, which was converted without further purification.
