Procedure

A solution of Example 222B (0.255 g, 0.620 mmol) in dichloromethane (5 mL) was treated with trifluoroacetic acid (0.477 mL, 6.20 mmol) and the mixture was stirred for 3 hours and concentrated. The residue was dissolved in 2 mL methanol and treated slowly with 2 mL 2M hydrogen chloride in ether. The suspension was diluted with ether and stirred for 10 minutes. The solids were filtered, washed with ether, and dried to give the title compound as a hydrochloride salt. MS (ESI+) m/z 312.1 (M+H)+.
