Reaction Steps

To a solution of 2(S)-{[7-(4-tert-Butyl-phenoxy)-1-cyclopentylmethyl-isoquinoline-3-carbonyl]-amino}-3-(5-vinylthiophen-2-yl)-propionic acid methyl ester (prepared in Example 9) (0.650 g, 1.09 mmol) in acetone:water was added methylmorpholine-N-oxide (0.340 mL) and osmium tetroxide (2 crystals). The solution was stirred at 0° C. for 1.5 h. Ethyl acetate was added and extracted with a solution of Na2S2O4(satd), brine, dried (Na2SO4), and concentrated under reduced pressure to give 0.600 g of 2(S)-{[7-(4-tert-Butyl-phenoxy)-1-cyclopentylmethyl-isoquinoline-3-carbonyl]-amino}-3-[5-(1,2-dihydroxy-ethyl)-thiophen-2-yl]-propionic acid methyl ester.
