実験手順

To 5-iodo-2-[(2S,4S)-4-methylpyrrolidin-2-yl]-1H-benzimidazole (2.29 g, 7.00 mmol) and (2S)-2-(methoxycarbonylamino)-3-methyl-butanoic acid (1.49 g, 7.70 mmol) in DMF is added HATU (3.46 g, 9.1 mmol) and DIPEA (2.4 mL, 14.0 mmol) at rt. The reaction mixture is stirred at rt overnight. To the reaction mixture is added water (350 mL) with fast stirring upon which a white solid precipitated out. The solid is suction filtered and dried under vacuum to give methyl N-[(1S)-1-[(2S,4S)-2-(5-iodo-1H-benzimidazol-2-yl)-4-methyl-pyrrolidine-1-carbonyl]-2-methyl-propyl]carbamate (2.73 g, 81%).
