Reaction Steps

Triethylamine (430 mg, 0.592 mL, 4.25 mmol) was slowly added to a mixture of 4-chloro-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-amine (200 mg, 0.849 mmol; Example 12, Step G), (R)-2-methoxypropanoic acid (106 mg, 1.02 mmol) and bis(2-oxooxazolidin-3-yl)phosphinic chloride (238 mg, 0.934 mmol) in anhydrous dichloromethane (10 mL). The resulting mixture was stirred at room temperature for 16 hours. The mixture was concentrated, and the residue stirred in THF (5 mL) and treated with water (20 mL). The solid, which separated, was collected by filtration and washed with water then dried under vacuum to yield (R)—N-(4-chloro-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methoxypropanamide (263 mg, 96% yield) as a solid. 1H NMR (400 MHz, (CD3)2SO) δ 12.49 (br s, 1H), 9.48 (s, 1H), 8.59 (s, 1H), 7.89 (d, 1H), 3.93 (q, 1H), 3.41 (s, 3H), 1.36 (d, 3H).
