Participants

Reaction Steps

A mixture of example 23A (30 mg, 0.11 mmol), 6-formylindole (19.2 mg, 0.132 mmol) and solid supported cyanoborohydride (0.22 mmol) was shaken in 1:1 mixture tetrahydrofuran and acetic acid for 15 hours, filtered and concentrated. The residue was purified with a high throughput HPLC system to provide the desired compound as its bis TRIFLUOROACETIC ACID salt.
