実験手順: A solution of 2-chloro-N-(3-fluoro-2-methylphenyl)acetamide (47.2 g, 234 mmol) in conc. sulphuric acid (220 ml) was treated at ca. −20° C. (ethanol/water/CO2(s) bath) with conc. nitric acid (69%, 15.25 ml, 19 g, 235 mmol) over 30 minutes, keeping internal temperature ≦9° C. The reaction was complete at the end of the addition. The mixture was added to ice with vigorous stirring then left to stand overnight. Filtration, washing of the solid with water and drying afforded the product (54.6 g, 95%) containing ˜9% impurity. temperature ≦9° C The reaction was complete at the end of the addition The mixture was added to ice then left Filtration washing of the solid with water drying

実験手順: A solution of chloroacetyl chloride (38.4 ml, 480 mmol) in ethyl acetate (100 ml) was slowly added to a vigorously-stirred mixture of 3-fluoro-2-methylaniline (60 g, 480 mmol), saturated aqueous sodium bicarbonate (400 ml), ice (ca 100 g) and ethyl acetate (400 ml). Some solid formed then dissolved. After 1 hour the mixture was evaporated to removing the ethyl acetate) and filtered, washing with water. The resulting product was dried in vacuo (94.4 g, 98%).
