Participants

Reaction Steps

49 mg (0.38 mmol) of tetrahydro-2-furanylacetic acid, 19.3 mg (0.16 mmol) of 4-dimethylaminopyridine and 91 mg (0.47 mmol) of N′-(3-dimethylaminopropyl)-N-ethylcarbodiimide×HCl are added to 3 ml of DMF. 150 mg (0.32 mmol) of tert-butyl 4-({[5-amino-1-(2-fluorobenzyl)-1H-indol-2-yl]carbonyl}amino)phenyl-carbamate from Example XXIX are added. The mixture is stirred at RT for 5 hours. For work-up, the mixture is diluted and extracted with dichloromethane and aqueous hydrochloric acid. The organic phase is washed with sat. sodium bicarbonate solution, dried with sodium sulphate, filtered and concentrated under reduced pressure using a rotary evaporator. The residue is purified by preparative HPLC.
