tert-butyl methyl(3-(4-(4-(tetrahydro-2H-pyran-2-yloxy)benzoyl)-phenyl)prop-2-ynyl)carbamate → tert-butyl methyl(3-(4-(4-(tetrahydro-2H-pyran-2-yloxy)benzoyl)-phenyl)propyl)carbamate

Participants

Reaction Steps

A flask was charged with tert-butyl methyl(3-(4-(4-(tetrahydro-2H-pyran-2-yloxy)benzoyl)phenyl)prop-2-ynyl)carbamate (450 mg, 1 mmol), Riney Ni (0.2 eq), and 20 mL of methanol. The mixture was stirred under hydrogen at room temperature and atmospheric pressure for 2 h. After complete conversion (TLC monitoring), the catalyst was filtered off through a pad of celite, and washed with EtOAc. The filtrate was concentrated under reduced pressure to give the product (364 mg, 80% yield).
