Reaction Steps
A solution of 1.1 eq. of 4-(methylamino)pyridine (180, Aldrich, 19,551-0) in anhydrous DMF was stirred under an atmosphere of argon as 1.1 eq. of HOBT and 2.0 eq of DIPEA were added followed by 1.0 eq of N-(tert-butoxycarbonyl)glycine (Bachem, A-1730). The mixture was stirred for 1 hr, cooled in an ice-bath and 1.1 eq. of EDC.HCl was added. The reaction was stirred and allowed to reach rt overnight. Water was added to the reaction mixture and the solvents were evaporated under high vacuum. The residue was dissolved in ethyl acetate, washed with 0.15 M citric acid, sat. aq. NaHCO3, brine and dried over anhydrous Na2SO4. To afford 181.
