Procedure

Methyl 3-(cyclopropylmethoxy)-4-aminobenzoate (8.86 g) was dissolved in pyridine (80 mL) at room temperature under N2 atmosphere. Methanesulfonyl chloride (4.04 mL) was added and the mixture was stirred at r.t. for 18 hours. The reaction mixture was evaporated to dryness, the crude was treated with 1N HCl (500 mL) and extracted with CH2Cl2 (3×200 mL). The organic layer was dried over Na2SO4 and the solvent was evaporated off to yield 11.7 g of the desired intermediate.
