Yield:297756-32-2 1.4 g
Reaction Conditions:
with palladium 10% on activated carbon;hydrogen in methanol at 25; under 2585.81 Torr; for 6 h;
Steps:
3.S-15.2 Step 2.
Under an atmosphere of nitrogen, Pd/C (200.0 mg, 10%) was added to a solution of intermediate SI-30 (1.60 g, 6.08 mmol, 1.0 eq) in MeOH (50 mL). The mixture was degassed under vacuum and purged with H2 several times. The mixture was stirred under H2 (50 psi) at 25° C. for 16 h. Upon completion, the reaction mixture was filtered and concentrated to give SI-31 (1.40 g) as colorless oil which was used in step 3 without further purification.
