Procedure
A solution of EXAMPLE 239A (3 g) in dichloromethane (35 mL), trifluoroacetic acid (15 mL), and triethylsilane (1 mL) was stirred for 2 hours. The solution was concentrated, then concentrated from toluene, and left on high vacuum for 24 hours. The semi-solid was taken up in ether/hexane and filtered to provide the title compound as its trifluoroacetic acid salt.
