Participants

Reaction Steps

2-(2-Aminoethyl)pyridine (0.034 mL, 0.29 mmol) was added to a stirred, room temperature mixture of 4-({(2S,5R)-1-(tert-butoxycarbonyl)-5-[(R)-{[tert-butyl(dimethyl)silyl]oxy}(phenyl)methyl]pyrrolidin-2-yl}methyl)benzoic acid (100 mg, 0.190 mmol), HATU (87 mg, 0.228 mmol), and DIPEA (0.166 mL, 0.951 mmol) in DMF (1.9 ml). The resulting mixture was stirred at room temperature overnight. Upon completion, as determined by LC-MS, water was added, and the mixture was partitioned with EtOAc. The aqueous layer was extracted with EtOAc (3×), and the combined organic layers were washed with brine, dried with Na2SO4, filtered, and concentrated in vacuo to give the product that was used directly in the next step. LC-MS=630.3 (M+1)+.
