A solution of EXAMPLE 396A (3 g) in dichloromethane (35 mL), trifluoroacetic acid (15 mL), and triethylsilane (1 mL) was stirred for 2 hours. The solution was concentrated, then condensed from toluene, and left under high vacuum for 24 hours. The semi-solid was taken up in ether/hexane and filtered to give the title compound as its TFA salt.
