Reaction Steps

To a stirred slurry of N-[2-(3,4-dichlorophenyl)-4-pentenylbutyl]-N-[(carboxymethyl)methyl]-3-cyano-2-ethyl-1-naphthamide (0.51 g) and NaIO4 (0.47 g) in 100 mL 1:1 THF:H2O was slowly added 0.32 mL OsO4 solution (4% w/w in H2O). Mixture was stirred for 18 h, 10 mL sat'd Na2S2O3(aq) was added, THF was evaporated, and aqueous residue was extracted with DCM. Extracts were dried over Na2SO4, filtered, and concentrated. This gave 0.64 g of N-[2-(3,4-dichlorophenyl)-4-oxobutyl]-N-[(carboxymethyl)methyl]-3-cyano-1-naphthamide after purification by chromatography (100:1, DCM:MeOH); MS: m/z 511 (M+); 1H NMR (CDCl3) δ 9.53 (s), 8.25 (s), 7.79 (d), 7.70-7.20 (m), 6.89 (d), 6.73 (d), 6.48 (dd), 4.58-4.20 (m), 3.88 (s), 3.84 (s), 3.60-3.21 (m), 3.18-2.82 (m), 2.65-2.32 (m), 1.33 (t).
