YieldReaction ConditionsOperation in experiment
With pyridine; trichlorophosphate;dmap; at -15 - 100℃; for 0.08333330000000001h;Microwave; Example 51 tert-Butyl 4-{4-[({4-[(E,Z)-[(3-bromo-4-fluorophenyl)amino](hydroxyimino)methyl]-1,2,5-oxadiazol-3-yl}amino)carbonyl]benzyl}piperazine-1-carboxylate trifluoroacetate A solution of 3-(4-amino-1,2,5-oxadiazol-3-yl)-4-(3-bromo-4-fluorophenyl)-1,2,4-oxadiazol-5(4H)-one (30 mg, 88 mumol), <strong>[479353-63-4]4-[4-(tert-butoxycarbonyl)piperazin-1-yl]methyl}benzoic acid</strong> (84 mg, 0.26 mmol), and 4-dimethylaminopyridine (6.4 mg, 53 mumol) in pyridine (0.75 mL) was treated with phosphoryl chloride (25 muL, 0.27 mmol) dropwise at -15 C. The reaction mixture was heated in a microwave at 100 C. for 5 min. The reaction mixture was concentrated to residue which was rediluted with methanol (1 mL), treated with 2.0 M sodium hydroxide in water (0.3 mL, 0.6 mmol), and stirred for 30 min. The reaction mixture was quenched with acetic acid (50 muL, 0.9 mmol), filtered, and purified by preparative LCMS to give the desired product (29 mg, 45%). LCMS for C26H30BrFN7O5 (M+H)+: m/z=618.0, 620.0.
