Reaktionsschritte

An aqueous solution of sodium hydroxide (1.24 g of 50% NaOH diluted with 5 ml of water) was added to a solution of N'-t-butyl-N-(2-pyridinecarbonyl)hydrazine (1.0 g, 0.00518 mol) in 20 ml of toluene at 23° C. The mixture was cooled and treated with 2-bromobenzoyl chloride (1.137 g, 0.00518 mol). The mixture was then stirred at 23° C. overnight. The solids were removed by filtration, washed with water and dried to afford 0.96 g of N'-t-butyl-N-(2-pyridinecarbonyl)-N'-(2-bromobenzoyl)hydrazine as a white solid: m.p. 179°-180° C.
