  • [1-(2,5-dimethyl-2H-pyrazol-3-ylmethyl)-2-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl]-acetic acid methyl ester [ No CAS ]
YieldReaction ConditionsOperation in experiment
71 a) To a stirring solution of (2,5-dimethyl-2H-pyrazol-3-yl)-methanol (100 mg, 0.79 mmol) in diethyl ether (3 mL) is added PBr3 (25 muL, 0.26 mmol). The reaction is stirred at room temperature for 18 hours, then water is added. The diethyl ether layer is separated and stored over solid NaOH and used in Step 71 b without further characterization. 71b) BEMP (137 pL, 0.47 mmol) is added to a solution of (2-methyl-1H-pyrrolo[2,3- b]pyridin-3-yl)-acetic acid methyl ester (60 mg, 0.29 mmol) in DMF (0.8 mL). After 35 minutes, the diethyl ether layer from Step 71 a (1.8 mL) is added. After 3 days, the reaction is partitioned between water and 1:1 EtOAc/ether. The organic layer is washed with brine then evaporated. The residue is purified by flash column chromatography (49:1 EtOAc/MeOH elution) to furnish [1-(2,5-dimethyl-2H-pyrazol-3-ylmethyl)-2-methyl-1H- pyrrolo[2,3-b]pyridin-3-yl]-acetic acid methyl ester; MH+ = 313.

YieldReaction ConditionsOperation in experiment
[2-Methyl-1-(3-methyl-3H-benzotriazol-5-ylmethyl)-1 H-pyrrolo[2,3-b]pyridin-3-yl]- acetic acid methyl ester: To a solution of (2-methyl-1 H-pyrrolo [2,3-b]pyridin-3-yl)-acetic methyl ester ( (0.025 g, 0.122 mmol) in dry DMF (1 ml) under an inert atmosphere of Argon is added dropwise, BEMP (56.6 pl, 0.196 mmol). The mixture is agitated at room temperature for 1 hour before cooling to 0 C with an ice-bath. A solution of 5-bromomethyl-1-methyl-1 H- benzotriazole (0.044 g, 0.196 mmol) in DMF (1 ml) is added to the cooled solution and the resulting mixture is agitated at room temperature for 2 days. The solvent is removed in vacuo and purification of the crude by chromatography on silica eluting with iso- hexane/ethyl acetate (0 %- 20 % ethyl acetate) yields the titled product. (MH+ 350).
