Lithium Hydroxide → HCID 60205680, compound

Participants

Reaction Steps

5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (0.5 g, 2.17 mmol; Example 1, Step H), (R)-2-methoxypropanoic acid (0.475 g, 4.56 mmol), BOP-Cl (1.16 g, 4.56 mmol), and triethylamine (1.51 mL, 10.9 mmol) were placed in DCM (5 mL) and stirred at room temperature for 1 hour. 3M aqueous LiOH (3 mL) was then added. The reaction was stirred for 10 minutes, then poured into water, and extracted with DCM. The combined organic fractions were dried (MgSO4), filtered, and concentrated to give the crude product, which was purified by silica gel chromatography (500:15 DCM:MeOH) to give (R)-N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methoxypropanamide.
