Methyl 3-chloro-5-isopropoxy-4-methoxybenzoate (4) (1.06 g, 95%) was prepared from methyl 3-chloro-4-hydroxy-5-isopropoxybenzoate (3) (1.00 g, 4.09 mmol) using a procedure essentially the same as in step (i) for AAA-001 except that methyl iodide was used instead of cyclopentyl bromide and the mixture was stirred at RT for 18 h.
