Reaction Steps
The Boc protected indole (200 mg, 1.5 mmol) prepared from 7-bromoindole and N-Boc piperazine as described in Step 1 of Preparation 54A is dissolved in DCM (1 mL). TFA (1 mL) is added and the mixture is stirred at r.t. for about an hour. The mixture is then concentrated to oil, which is taken up in methanol and freebased via SCX purification to afford about 164 mg (54%) of the final compound.
