Reaction Steps

Methyl 10-[[(dimethylamino)(oxo)acetyl](methyl)amino]-3-hydroxy-8-methyl-4-oxo-4,6,7,8,9,10-hexahydropyrimido[1,2-d][1,4]diazepine-2-carboxylate prepared as described in Step 2 was dissolved in methanol and treated with 1.2 eq. of triethylamine and 1.2 eq. of 4-fluorobenzylamine. The reaction mixture was refluxed overnight, then cooled to room temperature and purified by RP HPLC (C18, 5 μM, H2O/MeCN with 1% of TFA as eluant) affording desired compound (trifluoroacetic salt) as a white solid. 1H NMR (300 MHz, CD3CN) δ 12.4 (bs, 1H), 10.01 (bs, 1H), 7.63 (dd, J=8.6 Hz, J=5.7 Hz, 2H), 7.29 (t, J=8.6 Hz, 2H), 5.53-5.30 (m, 2H), 4.82-4.68 (m, 2H), 4.25-4.13 (m, 3H), 3.95 (bs, 1H), 3.48-3.42 (m, 1H), 3.25 (s, 3H), 3.20 (s, 3H), 3.19 (s, 3H), 3.13 (s, 3H); MS (ES) C22H27FN6O5 requires 474. Found: 475 (M+H+).
