Reaction Steps
(5-Bromo-pyridin-3-yl)-hydroxy-acetic acid HCl salt (1.19 g, 4.47 mmol), diphenylmethylamine (1.3 g, 5.36 mmol), HOAT (2.0 g, 5.36 mmol) and DIEA (1.94 mL, 11.17 mmol) were all combined in THF (43.0 mL) and heated in a closed vial for 20 min at 60° C. The solution was diluted with ethyl acetate and washed with saturated sodium bicarbonate (1×) and brine (1×). The material was purified by silica gel chromatography using a gradient of hexanes and ethyl acetate (0-100%) to afford N-benzhydryl-2-(5-bromo-pyridin-3-yl)-2-hydroxy-acetamide (1.5 g, 73.5%) as a waxy white solid. MS: m/z 397 (M+H+).
