Mode opératoire

A mixture of the title compound of Step B (127 mg, 0.29 mmol), cyclopropanecarboxamide (74 mg, 0.87 mmol), trifluoroacetic acid (0.07 mL, 0.87 mmol) and triethylsilane (0.14 ml, 0.87 mmol) in toluene (2 mL) was gently refluxed overnight. The reaction mixture was then concentrated under reduced pressure, and the residue was purified by column chromatography on silica gel using hexane/EtOAc as eluent to provide the title compound, a compound of this invention, as a white foamy solid (113 mg, 77% yield).
