Reaction Steps

A mixture of 5-bromopicolinamide 111 (0.588 g, 2.92 mmol) and 2,2-dihydroxy-1-(naphthalen-1-yl)ethanone 112 (1.20 g, 5.67 mmol) in dioxane (20 mL) were heated at 100° C. for 18 hours. The dioxane was removed under vacuum and the residue was dissolved in chloroform and methanol and concentrated onto silica gel. The material was purified by auto flash system (CH2Cl2 to 1% MeOH: CH2Cl2) to give 5-bromo-N-(1-hydroxy-2-(naphthalen-1-yl)-2-oxoethyl)picolinamide 113 as a tan solid (0.74 g, 66%).
