Application of 152120-54-2<\/a>, A common heterocyclic compound, 152120-54-2, name is tert-Butyl (((tert-butoxycarbonyl)amino)(1H-pyrazol-1-yl)methylene)carbamate, molecular formula is C14H22N4O4, 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

To a solution of N-alpha-Boc-D-lysine (13.0 g, 52.7 mmol) in EtOH (290 mL) was added N,N’-bis-Boc-1-guanylpyrazole (16.3 g, 52.7 mmol) and triethyl amine (10.6 g, 105 mmol). The reaction mixture was stirred at room temperature for 6 h. Solvent was removed and the residue was purified by column chromatography (silica gel, 10:1 CH2Cl2\/MeOH) to afford a pyrazole salt (25.0 g) as colorless oil. _The salt was dissolved in 1 N NaOH (300 mL) and neutralized with 1 N HCl (305 mL) The resulting precipitate was filtered out and dried, to afford compound 3 (22.0 g, 85%) as a white solid: 1H NMR (400 MHz, CDCl3) delta 11.48 (br s, 1H), 8.35 (br s, 1H), 5.23 (d, J=7.5 Hz, 1H), 4.23 (br s, 1H), 3.48-3.25 (m, 2H), 1.96-1.50 (m, 6H), 1.51 (s, 9H), 1.49 (s, 9H), 1.43 (s, 9H).<\/p>\n

The synthetic route of 152120-54-2 has been constantly updated, and we look forward to future research findings.<\/p>\n
