Reaction Steps

To a solution of 2-methoxy-(N-t-butyloxycarbonyl-4-piperidyloxy)benzoic acid (3.2 g; 9.1 mmol) from Step 3 of Example 25 in THF was added thionyl chloride (1 mL; 13.7 mmol) and pyridine (2 drops) while under a nitrogen atmosphere. The solution was stirred for 4 hours and then concentrated under reduced pressure to dryness. The residue was suspended in ether and filtered, and the filtrate was concentrated to dryness to yield 2-methoxy-(N-t-butyloxycarbonyl-4-piperidyloxy)benzoyl chloride.
