    أخرىThe product was purified by preparative TLC on silica plates

الإجراء التجريبي

Into a 20 mL vial was added (2S)-2-amino-N-{(1R)-2-cyclobutyl-1-[(3aS,4S,6S,7aR)-3a,5,5-trimethylhexahydro-4,6-methano-1,3,2-benzodioxaborol-2-yl]ethyl}-3-phenylpropanamide.HCl (46.3 mg, 0.109 mmol) (prepared as described in Example, THF (1.47 mL), N,N diisopropylethylamine (47.5 μL), and 6-phenoxy-3-pyridine sulfonyl chloride (32.4 mg.) The mixture was stirred at room temperature overnight. The product was purified by preparative TLC on silica plates using 50% ethyl acetate in hexanes to give 35 mg desired product as a white solid.
