Yield:147081-44-5 97%

Reaction Conditions:

with hydrogen;palladium on activated charcoal in methanol at 20; under 760.051 Torr; for 6 h;

Steps:

73.B
To a solution of product 178 (2.0 g, 9.42 mmol, 1.0 eq.) in 40 mL of methanol, palladium on charcoal (1.0 g, 0.94 mmol, 0.1 eq.) is added. The reaction medium is submitted to hydrogenation at atmospheric pressure and at room temperature for 6 hours. The reaction medium is then filtered on celite and concentrated under dry conditions under reduced pressure. The expected compound is obtained as a yellow oil (1.7 g, 97%).
