Procedure
To a suspension of the product of step C ((10.5 g, 36.0 mmol) in 15 mL of acetone was added 107 mL of 1N NaOH. After stirring at room temperature for 1 hour, the solution was acidified to pH 3 by the careful addition of 2N HCl. The mixture was extracted (2×) with EtOAc, dried (MgSO4), and concentrated under reduced pressure affording 8.35 g (87%) of 2-amino-5-[[(1,1-dimethylethoxy]carbonyl]amino]-6-methylbenzoic acid: Anal. Calc'd. for C13H18N2O4: C, 58.64; H, 6.81; N, 10.52. Found: C, 58.26; H, 6.72; N, 10.42.
