Into a 50-mL round-bottom flask, was placed a solution of tert-butyl 4-(4-((trimethylsilyl)ethynyl)phenyl)piperidine-1-carboxylate (compound 76.2, 1.34 g, 3.75 mmol) in tetrahydrofuran (20 mL). Tetrabutylammonium fluoride (1.95 g, 7.47 mmol) was added and the resulting solution was stirred for 10 min at room temperature. The mixture was diluted with water (30 mL) and extracted with EtOAc (3×20 mL). The organic layers were combined, dried (Na2SO4), filtered and concentrated under reduced pressure to yield the title compound as a brown oil (1.0 g, crude).
