Versuchsvorschrift

Following the procedure described for Preparation 13(A), 1-phenyl-4H,6H-2,3,6,10b-tetraaza-benzo[e]azulen-5-one (Preparation 4(A)) (5.0 g, 18.1 mmol) was alkylated with tert-butyl bromoacetate (2.94 mL, 19.9 mmol). Trituration with Et2O (100 mL), hexanes (30 mL) and EtOAc (10 mL) provided 3.13 g of (5-oxo-1-phenyl-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl)-acetic acid tert-butyl ester. 1H NMR (CD3OD) δ 7.68 (d, 1H), 7.60-7.51 (m, 4H), 7.43 (m, 2H), 7.23 (t, 1H), 6.99 (d, 1H), 4.86 (d, 1H), 4.44 (d, 1H), 3.99 (d, 1H), 3.83 (d, 1H), 1.36 (s, 9H); MS 391.4 (M+1), 389.3 (M−1).
