YieldReaction ConditionsOperation in experiment
70% Acylation of azaindole, method B: Preparation of Methyl(5-azaindol-3-yl)-oxoacetate 2b: 5-Azaindole (1b) (0.5 g, 4.2 mmol) was added to a suspension of AlCl3 (2.8 g, 21.0 mmol) in CH2Cl2 (100 ml). Stirring was continued at room temperature for 1 hour before methyl chlorooxoacetate (2.5 g, 21.0 mmol) was added dropwise. The reaction was stirred for 8 hours. After 20 ml of MeOH was added cautiously to quench the reaction, solvents were removed under vacuum. The solid residue was purified by silica gel column chromatography (EtOAc/MeOH=10:1) to afford 0.6 g (70%) of the acylated product 2b. Characterization of compounds 2: Compound 2b (Methyl(5-azaindol-3-yl)-oxoacetate): 1H NMR (500 MHz, CD3OD) δ 9.61 (s, 1H), 9.02 (s, 1H), 8.59 (d, 1H, J=6.63 Hz), 8.15 (d, 1H, J=6.60 Hz), 4.00 (s, 3H); 13C NMR (125 MHz, CD3OD) δ 178.9, 163.0, 145.6, 144.2, 138.3, 135.0, 124.7, 116.3, 112.1, 53.8. MS m/z: (M+H)+ calcd for C10H9N2O3: 205.06; found 205.04. HPLC retention time: 0.32 minutes (column A).
AlCl3; In dichloromethane; Preparation of Methyl (5-azaindol-3-yl)-oxoacetate 2b: 5-Azaindole 1b (0.5 g, 4.2 mmol) was added to a suspension of AlCl3 (2.8 g, 21.0 mmol) in CH2Cl2 (100 ml).
