Versuchsvorschrift

A mixture of p-hydroxybenzamide (3.43 g), methyl bromoacetate (2.37 ml) and K2CO3 (3.45 g) was stirred for 12 hr in 25 ml of DMF. The reaction mixture was diluted with water (150 ml); the solid was filtered, washed with water, and air dried. Crystallization from ethanol gave 3.3 g (63%) of the title compound as white crystals.
