Participants

Reaction Steps

45 mg (0.07 mmol) of the compound from Example 134 were initially charged in 1 ml of DMF, and 13 mg (0.09 mmol) of HOBt and 18 mg (0.09 mmol) of EDC were added. After 10 min of stirring at RT, 80 μl (1.44 mmol) of ammonia solution (35% strength in water) were added, and the mixture was stirred at RT for 16 h. Under reduced pressure, the reaction solution was then freed of excess ammonia, about 3 ml of water were added and the mixture was extracted three times with in each case 5 ml of ethyl acetate. The combined organic phases were dried over magnesium sulfate, filtered and concentrated under reduced pressure. The crude product was purified chromatographically [Method 19]. This gave 20 mg (46% of theory) of the target compound.
