Reaction Steps

1.17 g of HOAT, 1.60 g of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and 0.615 g of cyclobutylamine are added to a solution of 2.0 g of (4R)-1-(tert-butoxycarbonyl)-4-hydroxy-L-proline in 20 ml of DMF. 1.5 ml of a saturated solution of NaHCO3 is added and the reaction mixture is filtered on a Chem Elut® cartridge, eluting with DCM. The solvents are concentrated under vacuum and the residue is purified by filtration on silica gel, eluting with EtOAc. 1.22 g of the expected compound is obtained.
