8-tert-butyl 2-methyl 10-[benzyl(methyl)amino]-3-hydroxy-4-oxo-6,7,9,10-tetrahydropyrimido[1,2-d][1,4]diazepine-2,8(4H)-dicarboxylate (see Example 11, Steps 1-4) was dissolved in MeOH, treated with 1 N HCl (1 eq.) and stirred overnight under an H2 atmosphere in the presence of 10% Pd/C. The catalyst was then filtered off through celite, and the filtrate was concentrated under reduced pressure. MS (ES) C16H24N4O6 requires 368. Found: 369 (M+H+). The crude organic product was taken in methanol and treated with 1.2 eq. of 3-chloro-4-methyl-benzylamine and resulting mixture was refluxed overnight. After cooling to room temperature, evaporation of volatiles under reduced pressure yielded title product which was directly taken in the next step. MS (ES) C23H30ClN5O5 requires 491. Found: 492 (M+H+).
