Reaction Steps

A mixture of DIPEA (1,145 ml, 6.55 mmol) and (S)-pyrrolidine-2-carbonitrile 4-methylbenzenesulfonate (0.567 g, 2,114 mmol) in DCM was added to a mixture of (R)-2-(tert-butoxycarbonylamino)propanoic acid (0.4 g, 2.114 mmol) and HATU (0.804 g, 2.114 mmol) in DMF. After 3 h the mixture was washed with 1N citric acid and saturated sodium bicarbonate and brine. The organic layer was dried sodium sulfate, filtered and purified by column chromatography with a gradient DCM to DCM-MeOH (95-5). (0.47 g, 83%)
