Yield:126300-39-8 98.1%
Reaction Conditions:
with palladium 10% on activated carbon;hydrogen;glacial acetic acid in methanol;lithium hydroxide monohydrate at 25; for 20 h;
Steps:
1.4; 2.4 Step (4)
to a 250 mL round-bottom flask, add 3.60 g of compound 4a (11.24 mmol, 1.00 eq), methanol (54 mL), and acetic acid (0.72 g). After nitrogen displacement, a Pd/C catalyst (10% Pd, containing 55% water) (1.2 g) was added, followed by hydrogen substitution, and atmospheric hydrogenation at 25 °C for 20 h. Add 2 g of activated charcoal, stir, filter and wash the cake with 20 mL of methanol. Concentrated under reduced pressure, dried in vacuum, colorless oil 5 (1.55 g, yield 98.1%).
