Procedure

A solution of acetic acid 3-(5-bromo-1H-pyrrolo[2,3-b]pyridine-3-carbonyl)-2-methyl-phenyl ester (84, 25.0 mg, 0.067 mmol) in 6 N HCl (4.0 mL) was heated with a CEM Discover microwave instrument at 110° C. for 10 min. The reaction mixture was poured into water, neutralized with 1 M aqueous potassium carbonate, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated. The desired compound was isolated by silica gel column chromatography eluting with 10% ethyl acetate in hexane to give a colorless oil (P-0055, 4.7 mg, 21%). MS(ESI) [M−H+]−=329.0, 331.0.
