Procedure
To a stirred solution of (R)-3-acetyl-4-(3-cyclopentyloxy-4-methoxyphenyl)-3-methyl-pyrrolidine-1-carboxylic acid methyl ester (see Example 12 of Feldman et al. U.S. Pat. No. 5,665,654, incorporated herein by reference) (or (R)-3-acetyl-4-(3-cyclopentyloxy-4-methoxyphenyl)-3-methyl-pyrrolidine-1-carboxylic acid methyl ester) (0.133 mmol, 50 mg) in methanol (2 mL) with catalytic amount of acetic acid (20 μL) was added methyl hydrazine (0.147 mmol, 7.8 μL). The reaction was heated gently for 36 hours, and three more portions of methl hydrazine were added. The resulting hydrazone was purified by HPLC. The named product was confirmed by HNMR.
