The chemical industry reduces the impact on the environment during synthesis 811442-84-9, name is tert-Butyl (14-amino-3,6,9,12-tetraoxatetradecyl)carbamate, I believe this compound will play a more active role in future production and life. 811442-84-9
200 mg (0.594 mmol) of tert-butyl (14-amino-3,6,9,12-tetraoxatetradec-1-yl)carbamate, 111 mg (0.713 mmol) of (2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetic acid and 410 mul (2.4 mmol) of N,N-diisopropylethylamine were dissolved in 6 ml of dimethylformamide, and 339 mg (0.892 mmol) of HATU were added. The reaction mixture was stirred at RT for 1 h and purified directly by preparative RP-HPLC (column: Reprosil 250*30; 10mu, flow rate: 50 ml/min, MeCN/water/0.1% TFA). The solvents were evaporated under reduced pressure and the residue was dried under high vacuum. This gave 130 mg (43% of theory) of tert-butyl [17-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)-16-oxo-3,6,9,12-tetraoxa-15-azaheptadec-1-yl]carbamate. LC-MS (Method 1): Rt=0.71 min; MS (ESIpos): m/z=474 (M+H)+.
