Participants

Reaction Steps

A mixture of 50 mg (75 μmol) of the compound of Example 39, 29 mg (0.15 mmol) of EDC and 20 mg (0.15 mmol) of HOBt in 2 ml of DMF was stirred at RT for 20 min and then poured into 5 ml of ammonia (35% strength solution in water). The reaction mixture was stirred at RT for 30 min and then concentrated on a rotary evaporator, acidified with 2.5 N hydrochloric acid and separated by preparative HPLC [Method 6]. The appropriate fraction was concentrated on a rotary evaporator and the residue was dried under high vacuum. This gave 42 mg (84% of theory) of the title compound.
