Reaction Steps

Compound 11 (0.2 g, crude, max. 0.22 mmol) was stirred in a mixture of DCM (5 mL) and TFA (3 mL). After 2 h the solution was concentrated and remains of TFA were removed by repeated concentration in toluene (3×5 mL). The product was purified by preparative HPLC-MS to give compound 12 in pure form (0.11 g, 56% over the three steps from 9).
