Participants

Reaction Steps

2.26 g (R)-2-Oxo-1-((R)-1-phenyl-ethyl)-3-(toluene-4-sulfonyl)-imidazolidine-4-carboxylic acid (1R,2S,5R)-2-isopropyl-5-methyl-cyclohexyl ester (I.24) was placed in 20 mL tetrahydrofuran at 0° C. under nitrogen, then 1.12 mL lithium aluminium hydride (2.3M in tetrahydrofuran) was added. The reaction was stirred for 1 h 45 min and then a 10 mL of a saturated solution of sodium sulfate was added. The mixture was extracted with ethyl acetate (×2), dried over sodium sulfate, filtered and the solvent was removed under reduced pressure. Purification by silica gel chromatography (dichloromethane/ethyl acetate 100:0 to 70:30) gave the title compound.
