Versuchsvorschrift

To a solution of 4-benzyloxy-3-methoxyphenylacetic acid (5.0 g, 18 mmol), from Step 2, in THF (40 mL) was added oxalyl chloride (2.54 g, 20 mmol, 1.1 equivalent) followed by a catalytic amount of DMF (~0.2 mL). The resulting mixture was stirred at ambient temperature for 2 hours and then concentrated under reduced pressure to give the title compound which was used without purification.
