Procedure

Triphenylphosphine (374 mg, 1.43 mmol) was dissolved in 25 mL of DCM followed by addition of I2 (362 mg, 1.43 mmol) and TEA (289 mg, 2.85 mmol) at 0° C. N′-((2R,3S)-3-(tert-butyldimethylsilyloxy)-2-(4-cyano-2-methyl-3-(trifluoromethyl)phenylamino)butanoyl)-4-cyanobenzohydrazide (400 mg, 0.71 mmol) in 15 mL DCM was added to the precooled solution mixture of PPh3/I2/TEA system and stirred. The temperature was allowed to rise to room temperature and stirred for an additional 10 min. The reaction was quenched with 50 mL saturated sodium thiosulfate and extracted with EtOAc. The crude mixture was chromatographed to give the product (380 mg) 1H NMR (400 MHz, acetone-d6, δ in ppm): 8.39 (d, J=9 Hz, 2H), 8.19 (d, J=9 Hz, 2H), 7.79 (d, J=9 Hz, 1H), 7.32 (d, J=9 Hz, 1H), 5.88 (d, J=9 Hz, 1H), 5.53 (m, 1H), 4.99 (m, 1H), 2.61 (m, 3H), 1.67 (d, J=6 Hz, 3H), 1.02 (s, 9H), 0.29 (s, 3H), 0.00 (s, 3H).
