pentyl 2-aminobenzoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 450 parts of anthranilic acid methyl ester, 500 parts of n-pentanol and 10 parts of potassium carbonate are reacted as described in Example 1. The reaction lasts for about 8 hours. There are obtained 588 parts of anthranilic acid n-pentyl ester (boiling point 132°-135° C. under 0.3-0.4 mm Hg; nD25 1.538; purity according to gas chromatography 99%, below 0.2% of anthranilic acid methyl ester). Yield: 95% of the theory.
