Procedure

A solution of crude N-(4-fluorobenzyl)-3-hydroxy-8-(methylamino)-4-oxo-6,7,8,9-tetrahydro-4H-pyrido[1,2-a]pyrimidine-2-carboxamide, 1-hydroxybenzotriazole (2 eq.), 1-(3-dimethylaminopropyl)-3-ethyl-carbodiimide hydrochloride (2 eq.), DIPEA (1 eq.) and acetic acid (2 eq) in dichloromethane was stirred for 16 h at room temperature. The solvent was removed under vacuum and the product was isolated by prep. RP-HPLC, using water (0.1% TFA) and acetonitrile (0.1% TFA) as eluents (column: C18). After lyophilization the product was obtained as a fluffy white material.
