1334177-86-4, 1-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)-3-oxo-7,10,13,16,19,22,25,28-octaoxa-4-azahentriacontan-31-oic acid is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
EDCI.HCI (46 mg, 0.24 mmol) was added to a solution of 145 and Mal-PEG8-acid (130 mg,0.22 mmol) in CHCI3 (10 mL) and stirred at room temperature for 2 hr. LC/MS shows 78%starting material present. A further 2 eq EDCI.HCI was added in portions to push the reaction to completion. The reaction mixture was washed with water (10 mL), dried (Biotage PS) and evaporated to dryness, under reduced pressure, to leave a yellow solid which was purified by prep HPLC to leave the product I as an off-white solid (90 mg, 34%yield). LC/MS (method B): retention time 1.47 mins, (ES+) rnlz 1445.9 [M+ H].
