Yield:1240390-32-2 600 mg

Reaction Conditions:

with 10 wt% Pd(OH)2 on carbon;hydrogen in ethanol; under 1551.49 Torr; for 15 h;

Steps:

177.4

Step 4: To a solution of (3S,4S)-3 -((S)-1-phenylethylamino)tetrahydro-2H-pyran-4-ol (1.47 g, 6.65 mmol) in EtOH (25 ml) was added Pd(OH)2/C (200 mg), charged with H2 (30 psi) in a parr shaker, and was shaked for 15 h, Pd(OH)2/C was filtered off, the filtrate was concentrated to give (3S, 4S)-3-aminotetrahydro-2H-pyran-4-ol (600 mg).
