実験手順

To a mixture of tert-Butyl (2R,5R)-2-[2-(3-{[N-(tert-butoxycarbonyl)-4-fluoro-β-(4-fluorophenyl)-L-phenylalanyl]amino}-5-fluoropyridin-4-yl)ethyl]-5-(hydroxymethyl)morpholine-4-carboxylate (Example 149, Step 7) (677 mg, 0.95 mmol) and carbonyldiimidazole (154 mg, 0.95 mmol) was added dry pyridine (22.5 mL). The resulting solution was heated at 60° C. and stirred for 2 h. This solution was then distributed in 0.5 mL (0.021 mmol) aliquots to 45 2-dram sample vials, each containing a diverse amine (0.042 mmol); among them (6-chloropyridin-2-yl)methanamine. The resulting mixtures were stirred at 60° C. for 3 h. Solvent was removed under stream of N2 gas. The residues were diluted with 4 N HCl/diethyl ether (1 mL) and stirred at room temperature for 16 h. Solvent was removed under stream of N2 gas, and the residues were diluted with DMSO and purified by mass-guided reversed-phase HPLC (10-90% CH3CN:0.1% NH4OH/H2O). HRMS (ES) 683.2353 (M+H). found, 683.2355 required.
