Sodium Hydroxide → HCID 178422428, compound

Participants

Reaction Steps

A mixture of N-(4-bromo-2-carbamoyl-6-methylphenyl)nicotinamide (1.74 g salt, 5.22 mmol, 1.0 eq) in EtOH (50 mL) was treated with NaOH (1.04 g, 26.1 mmol, 5.0 eq). The resulting mixture was stirred at room temperature overnight. After the reaction was completed, the volatiles were removed in vacuo. Water (30 mL) was added to the residue and the mixture was adjusted to pH˜1 or 2 by slow addition of aqueous HCl. The resultant precipitate was collected and dried to give 870 mg of iv-h as a yellow solid (77% yield after two steps), LCMS m/z=315.7, 317.7 (M+1) (Method B) (retention time=1.74 min).
