Yield:112-92-5 52 %Spectr. ，2778-96-3 10 %Spectr.

Reaction Conditions:

with Ru(OAc)2(1,4-bis(diphenylphosphino)butane);hydrogen in toluene at 160; under 15001.5 Torr; for 24 h;Inert atmosphere;

Steps:

3

General procedure: 3-phenylpropionic acid (150.2 mg, 1.0 mmol), the ruthenium complex b (18.2 mg, 0.020 mmol) obtained in Synthesis Example 1, and a magnetic stirring bar were placed in a glass tube. The glass tube was inserted into the autoclave, the autoclave was tightly closed, evaporated under vacuum and filled with argon gas. Dehydrated toluene (3.0 mL) was added to the mixture while continuing the flow of argon gas, and the interior of the autoclave was purged several times with hydrogen gas (PH 2 = 1.5 MPa). The autoclave was pressurized with hydrogen gas (PH 2 = 1 MPa) at 25 ° C. and heated at 160 ° C. for 24 hours with stirring (1000 rpm). The autoclave was cooled to 0 ° C. in an ice water bath. The reaction mixture was transferred to a 100 mL round bottom flask together with chloroform and concentrated under reduced pressure (about 35 mm Hg, 40 ° C.). The residue was diluted with CDCl 3 and analyzed by H NMR. The yields of 3-phenylpropyl alcohol and 1- (3-phenylpropyl) 3-phenylpropionate (35% and 18%, respectively) are based on the integral ratio between the signals of these compounds to the internal standard (mesitylene) .
