実験手順
Hexadecandioic acid (2 g, 7 mmol) was dissolved in dry NMP (25 mL). Diisopropylamin (1.2 mL, 7 mmol) and 4-methoxybenzyl chloride (0.95 mL, 7 mmol) was added, followed by NaI (0.52 g, 3.5 mmol). The mixture was heated to 80° C. for 1 hour, poured into water (100 mL) and filtered. The precipate was washed with dichloromethane (150 mL), the dichoromethane phase was dried (Na2SO4) and solvent removed in vacuo to yield the crude product, which was recrystalized several times from heptane to yield hexadecanedioic acid mono-(4-methoxy-benzyl) ester.
