Procedure

Preparation of example 34 from the title compound of Example 33 (40 mg, 0.078 mmol), and 1:1 TFA/CH2Cl2 (5 mL) was carried out analogously to Example 20. Isolation, also in an analogous manner, included a further trituration with methanol/diethyl ether and afforded the title compound (10 mg, 0.019 mmol) as an orange/yellow powder in 24% yield.
