Reaction Conditions

Reaction Steps

To a suspension of methyl 2-amino-5-chloro-3-methylbenzoate (i.e. the product of Example 2) (4.03 g, 20.2 mmol) in acetonitrile (12.4 g) was added a solution of methylamine (3.1 g, 0.10 mol) in ethylene glycol (12.4 g). The mixture was heated at 60° C. for 23 h, and then cooled to room temperature. Water (25 mL) was added dropwise, and the resulting slurry was cooled to 5° C. and stirred for 10 minutes at this temperature. The mixture was filtered, and the solids were washed with water (3×10 mL), and dried under nitrogen to afford the title compound as white needles, 3.43 g (85.5% yield).
