Procedure

(2S,4R)-1-(tert-butoxycarbonyl)-4-(4-chloroisoindoline-2-carbonyloxy)pyrrolidine-2-carboxylic acid 26 (0.35 g, 0.852 mmol), (1R,2S)-1-amino-2-cyclopropyl-N-(cyclopropylsulfonyl)cyclopropanecarboxamide hydrochloride 25 (0.287 g, 1.02 mmol) and HATU (0.389 g, 1.02 mmol) were dissolved in DriSolve DMF (8.5 mL), and cooled in an ice bath. DIEA (d 0.742) (0.445 ml, 2.56 mmol) was then added to reaction drop-wise. The reaction was allowed to warm up to rt slowly and stirred overnight. After reaching completion, the reaction was diluted with water (120 mL) and extracted with EtOAc (3×150 mL). The combined organic extract was washed with 0.5 N HCl (200 mL), brine (150 mL) and dried over Na2SO4. Removal of solvent yielded the crude product as a light yellowish foamy solid, which was purified by reverse phase chromatography (eluent: 5 to 95% MeCN/water), giving pure desired product as a white solid (0.40 g, 70% yield). LCMS (APCI+): 537.2 (MH+−Boc).
