Versuchsvorschrift

136 mg of 80% sodium hydride in oil are added to a solution of 8 g (16mmol) of benzyl 6-[3-(1-adamantyl)-4-hydroxyphenyl]-2-naphthoate in 100 ml of DMF. The mixture is left stirring for 1 h and 1.6 ml (16.4 mmol) of methyl bromoacetate are added. The reaction mixture is left stirring overnight, and it is then poured into ice cold water and acidified to pH 2 with concentrated HCl. The solid is filtered and recrystallized from ether. 8.52 g (95%) of the expected derivative are recovered, which derivative melts at 183° C.
