Yield:53617-35-9 100%

Reaction Conditions:

with palladium on activated charcoal;hydrogen in isopropyl alcohol at 80; under 3750.38 Torr; for 7 h;Autoclave;Reagent/catalyst;

Steps:

11 Example 11

The compound (3) (120 g; 0.46 mol), 2-propanol (276 g), and the palladium/carbon catalyst (0.3 g in terms of metallic palladium) were placed in an autoclave with a capacity of 1 L, and then the whole was stirred at 80° C., under a hydrogen pressure of 0.5 MPa for 7 hours. After cooling the reaction, the catalyst was filtered and washed with 2-propanol to obtain a filtrate. The resulting filtrate was analyzed by gas chromatography. As a result, the yield of the compound (4) analyzed by the internal standard method was 97%, and the area percentage (excluding the solvent and the compounds with low boiling points) of the compound (4) was 100% (Table 2).
