Procedure
To a solution of N-[2-[(3-carboxyphenyl)thiomethoxy]-1(S)-cyanoethyl]-3-methyl-Nα-(2,2-diphenylacetyl)-L-phenylalaninamide (89 mg, 0.15 mmol) in acetone (5 mL) is added a solution of potassium peroxymonosulfate (Oxone®, 0.11 g, 0.18 mmol) in water (5 mL) at 0° C., and the solution is stirred at 0° C. for 40 minutes. 5% NaHSO4 (10 mL) is added, and the cloudy suspension is filtered. The solid is washed with water (50 mL), dried in vacuo, and then recrystalized (CH2Cl2, Et2O) to yield N-[2-[(3-carboxyphenyl)methanesulfinyl]-1(S)-cyanoethyl]-3-methyl-Nα-(2,2-diphenylacetyl-L-phenylalaninamide product, as a white solid, m.p. 170-171° C.
