Reaction Steps
Compound 201B (44 mg, 0.18 mmol) was treated with a mixture of CH2Cl2 and TFA (1:1, 2 mL) for 30 min. The volatiles were removed under reduced pressure and the residue was azeotropically evaporated with heptane-CH2Cl2 three times to give a TFA salt of Compound 201C, which was used immediately in the next reaction without step further purification.
