Reaction Steps

The product of step b) (2.6 g, 5.2 mmol) in CH2Cl2 (25 ml) and trifluoroacetic acid (TFA) (75 ml) was stirred at 22° C. for 16 hours. Next, the solvent was evaporated and toluene (50 ml) was added and subsequently evaporated in vacuo at 40° C. to remove residual TFA. The crude subtitle product was used without further purification.
