Electric Literature of 139756-02-8<\/a>, A common heterocyclic compound, 139756-02-8, name is 4-Amino-1-methyl-3-N-propyl-1H-pyrazole-5-carboxamide, molecular formula is C8H14N4O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.<\/p>\n

General procedure: To a solution of 2-aminobenzamide (1.470 mmol, 1.0 eq.) was added to a solution of Terminal Alkyne (1.470 mmol, 1.0 eq.), Tosyl Azide, (1.470 mmol, 1.0eq.), CuI (0.147 mmol, 0.1 eq.), triethylamine (2.941 mmol, 2.0 eq.), in acetonitrile (10 ml) under N2 atmosphere. The mixture was stirred at room temperature for 12 h. After completion of the reaction (as indicated by TLC) the reaction mixture was poured into water (25 mL) and extracted with ethyl acetate (2×25 mL), dried over Na2SO4, concentrated under vacuum to get crude compound which was purified by column chromatography using a mixture of petroleum ether: ethyl acetate to give the desired product as a white solid.<\/p>\n

The synthetic route of 139756-02-8 has been constantly updated, and we look forward to future research findings.<\/p>\n
