1,3-Dibromopropane → HCID 19389089, compound

Participants

Reaction Steps

A mixture of 4.0 g (7.67 mmol) of N-[3-hydroxy-5-(octadecyloxy)phenyl]-N-(2-methoxy-2-oxoethyl)glycine methyl ester, 7.8 ml (76.6 mmol) of 1,3-dibromopropane and 5.3 g (38.3 mmol) of potassium carbonate in 75 ml of acetone and 15 ml of DMF was stirred at reflux under argon for 41 hours. The reaction mixture was filtered through a Celite pad and the filtrate was concentrated to a solid which was purified by HPLC using 5% ethyl acetate-toluene to give 3.5 g (72% yield, mp 67°-69°) of N-[3-(3-bromopropoxy)-5-(octadecyloxy)phenyl]-N-(2-methoxy-2-oxoethyl) glycine methyl ester. The structure was confirmed by the nmr spectrum.
