2-amino-4-fluoro-6-methylbenzonitrile

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: N-Bromosuccinimide (16.6 g, 93.3 mmol) was gradually added to an N,N-dimethylformamide (250 ml) solution of 2-amino-4-fluoro-6-methylbenzonitrile (I-264) (14.0 g, 93.3 mmol). After stirring for 6 hours, the reaction liquid was poured into water with ice (750 ml), the precipitated solid was collected by filtration. The solid was washed with water, then dried to obtain the entitled compound (20.2 g, 95%) as a gray solid. the reaction liquid the precipitated solid was collected by filtration The solid was washed with water dried

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Acetic acid (16.0 ml, 28 mmol) was added to a concentrated hydrochloric acid (90 ml) solution of tin chloride dihydrate (63.1 g, 280 mmol), and 4-fluoro-2-methyl-6-nitrobenzonitrile (I-263) (16.8 g, 93.3 mmol) was added, then methanol (8 ml) was added. Since the reaction liquid greatly generated heat, it was cooled with ice. After stirring for 1 hour, the reaction mixture liquid was poured into aqueous sodium hydroxide solution (4.6 M, 500 ml) with ice therein. The precipitated solid was collected by filtration, washed with water, then dried to obtain the entitled compound (14.7 g, 99%) as a gray solid. was added Since the reaction liquid greatly generated heat it was cooled with ice The precipitated solid was collected by filtration washed with water dried
