Reaction Steps

A suspension of ethyl 3-hydroxy-4-methylbenzoate (14.42 g, 80 mmol) (from Example 32 supra) in anhydrous hydrazine (30 mL, 956 mmol) (Aldrich) was heated at reflux (150° C. bath temperature) for 2.0 hours. After cooling to room temperature, mixture was concentrated under reduced pressure (high vacuum) to give crude 3-hydroxy-4-methyl-benzoic acid hydrazide as an off-white solid. (Yield 13.26 g, 100%).
