Reaction Steps

To a solution of 4-(3,5-difluorophenyl)-3,6-dihydro-2H-pyran (1.0 equiv.) in methanol (0.2 M) was added 10% Pd/C (0.05 equiv.). The reaction was placed under an atmosphere of hydrogen and stirred for 18 hours. Upon completion, the solution was filtered over a pad of Celite, the pad was washed with DCM, the filtrate was concentrated in vacuo to give 4-(3,5-difluorophenyl)tetrahydro-2H-pyran in 71% yield. 1H NMR (400 MHz, <cdcl3>) δ ppm 1.76 (br. s., 4H), 2.75 (br. s., 1H), 3.50 (br. s., 2H), 4.08 (d, J=9.78 Hz, 2H), 6.56-6.94 (m, 3H).
