Reaction Steps

0.1 g of (3R,3aS,6aR)-hexahydrofuro[2,3-b]furan-3-yl (4S,5R)-5-{[(2,3-dihydro-1,4-benzodioxin-6-ylsulfonyl)(isobutyl)amino]methyl}-4-(4-hydroxybenzyl)-2,2-dimethyl-1,3-oxazolidine-3-carboxylate, 0.03 g of o-picolylchloride-hydrochloride and 0.15 g of cesium carbonate were suspended in 0.5 mL of dimethyl formamide and heated to 60 degrees for 3 h. The mixture was diluted with ethyl acetate and washed with water. Chromatography on silica gel (9:1 ethyl acetate/hexanes) gave 72 mg of the desired material
