[00474] EXAMPLE 42A. Synthesis of Compound 265.[00 4-bromo-N-methoxy-N,l-dimethyl-lH-pyrazole-3-carboxamide. A mixture of 4-bromo-l -methyl- lH-pyrazole-3-carboxylic acid (2.04 g, 10 mmol), 2-(lH-benzotriazole-l-yl)-l,l,3,3-tetramethyluronium tetrafluoroborate (3.21 g, 10 mmol), Nu,Omicron-dimethylhydroxylamine (1.22 g, 20 mmol) in N,N-Diisopropylethylamine (5 mL) and N,N-Dimethylformamide (20 mL) was stirred for 12 h at room temperature. The mixture was concentrated in vacuum, and the residue was purified by flash chromatography eluting with petroleum ether\/ethyl acetate = 5: 1 to give the titled product as a colorless oil (2.4 g, 97%). LC\/MS m\/z 247 [M+H]+.<\/p>\n
