Procedure

140 mg (0.96 mmol) of (2-methyl-1,3-dioxolan-2-yl)acetic acid are added to 5 ml of DMF, and 547 mg (1.44 mmol) of O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate and 186 mg (0.25 ml, 1.44 mmol) of N,N-diisopropylethylamine are added. 300 mg (0.96 mmol) of ethyl 5-amino-1-(2-fluorobenzyl)-1H-indole-2-carboxylate from Example XXXVI are added. The mixture is stirred at RT for 3 hours. For work-up the DMF is removed using a rotary evaporator. The residue is taken up in dichloromethane and extracted with aqueous hydrochloric acid. The organic phase is dried with sodium sulphate, filtered and dried under reduced pressure.
