80% | 1 Example 1 Product from the above stage (80.0 g, 149.4 mmol) was hydrogenated in isopropanol (880 ml) with 5% palladium on carbon (16 g, of a wet paste) and hydrogen pressure (approx 0.5 to 1.5 bar) at 25-50° C. for approximately 5 hours. The mixture was cooled and the catalyst removed by filtration. The solution was distilled to a volume of approximately 320 ml and water (80 ml) was added. This solution was divided into two for the crystallisation step. To half of the above solution, decolourising charcoal (2 g) was added, the mixture stirred at approximately 32° C. for 4 hours, then filtered. The filtercake was washed with isopropanol (20 ml) then further water (40 ml) was added to the filtrate. The solution was seeded to induce crystallisation and stirred for 5 hours. Water (130 ml) was added slowly over 1 hour then the mixture was stirred for 4 hours. The resultant slurry was cooled to approximately 20° C. and the product was isolated by filtration and washed with a 1:4 mixture of isopropano/water (120 ml). The product was dried at approximately 50° C., under vacuum, for approximately 12 hours to give (3S)-tetrahydro-3-furyl N-[(1S,2R)-3-(4-amino-N-isobutylbenzenesulphonamido)-1-benzyl-2-hydroxypropyl] carbamate (30.3 g; 80% of theory yield).
