In a similar manner to Example 2, starting material step (b), t-butyl bromoacetate (2.9 ml), 3-methyl-4-nitrophenol (2.5 g), anhydrous potassium carbonate (2.7 g) and acetone (100 ml) were reacted to give t-butyl 3-methyl-4-nitrophenoxyacetate (4.19 g) as an off-white solid: NMR Spectrum (DMSO-d6) 1.44 (9H, s), 2.56 (3H, s), 4.71 (2H, s), 6.94 (1H, dd), 7.03 (1H, d), 8.06 (1H, d); Mass Spectrum m/Z 268 (M+H)+.
