Adding a certain compound to certain chemical reactions, such as: 581065-95-4, name is tert-Butyl 1-amino-3,6,9,12-tetraoxapentadecan-15-oate, belongs to esters-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 581065-95-4, Recommanded Product: tert-Butyl 1-amino-3,6,9,12-tetraoxapentadecan-15-oate
To a stirred solution of 4-(4-(3-(4-chloro-3-(trifluoromethyl)phenyl)ureido)phenoxy)- picolinic acid (08) (200 mg, 0.44 mmol, 1.0 equiv) in DMF (5.0 mL, 25.0 vol. equiv), were added tert-butyl l-amino-3,6,9, 12-tetraoxapentadecan-15-oate (165 (171.0 mg, 0.53 mmol, 1.2 equiv), HATU (505 mg, 1.33 mmol, 3.0 equiv) and DIPEA (68.50 mg, 0.53 mmol, 1.20 equiv). The reaction mixture was stirred for 12 h at RT. Completion of the reaction was monitored by TLC. The Reaction mixture was quenched with DMW (100 mL) and extracted with EtOAc (100 mL x 3). The combined organic extract was washed with brine (100 mL), dried over Na2S04 and concentrated under vacuum to afford the titled compound (16) (160 mg, 47.90%) as a brownish gum. MR (300 MHz, OMSO-d6) delta 9.23 (s, 1H), 9.02 (s, 1H), 8.75 (s, 1H), 8.52- 8.51 (d, 1H), 8.13-8.12 (d, 1H), 7.64-7.63 (d, 2H), 7.61 (s, 1H), 7.58 (s, 1H), 7.38-7.37 (d, 1H), 7.19-7.16 (m, 3H), 3.58-3.44 (m, 18H), 2.51-2.49 (t, 2H), 1.38 (s, 9H). MS (ES+): 755.0 (M+l); MS (ES-): 753.3 (M-l). HPLC: 97.56%.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, tert-Butyl 1-amino-3,6,9,12-tetraoxapentadecan-15-oate, other downstream synthetic routes, hurry up and to see.
