Versuchsvorschrift
To a solution of 1-phenyl-4H,6H-2,3,6,10b-tetraaza-benzo[e]azulen-5-one (Preparation 4(A) (30.0 g, 108 mmol) in DMF (200 mL) at 0° C. was added NaHMDS (1.0M in THF, 13.6 g, 118 mmol) and N-benzyl-2-bromo-N-isopropyl-acetamide (Preparation 1 (C) (35.2 g, 130 mmol) in DMF (25 mL). The reaction was stirred at room temperature for 24 hours and was diluted with a pH 6.8 phosphate buffer. The aqueous solution was washed with EtOAc (3×). The combined organic solutions were washed with brine (3×), dried (Na2SO4), filtered and concentrated. Purification by medium pressure chromatography eluting with a solvent gradient (CH2Cl2 to 12% acetone in CH2Cl2) provided 13.9 g of N-benzyl-N-isopropyl-2-(5-oxo-1-phenyl-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl)-acetamide. 1H NMR (CDCl3) δ 7.64-7.55 (m, 2H), 7.44-7.08 (m, 11H), 6.89 (m, 1H), 4.96-4.08 (m, 6H), 3.57 (m, 1H), 1.17 (m, 6H).
