Procedure: To a stirred suspension of 95% lithium aluminum hydride (2.19 g, 58 mmol) in anhydrous THF (10 mL) at 0° C., was added dropwise a solution of N-(2-chloro-3-fluoro phenyl)-formamide (2.3 g, 13.2 mmol) in anhydrous THF (20 mL). The reaction mixture was allowed to slowly warm to room temperature and was stirred for a further 40 mins. The mixture was cooled to 0° C. and was quenched via the sequential addition of water (4 mL), 15% aq. NaOH (2 mL), then water (4 mL). Organics were extracted into a mixture of 3:1 DCM: IPA (100 mL) and washed with water (50 mL). The organic layer was separated and dried over MgSO4. Filtration then concentration in vacuo gave N-methyl-2-chloro-3-fluoroaniline 29-1 (2.07 g, 99%) as a yellow oil. MS (M+H)+: 160.1, tR=2.21 min (method 1). The mixture was cooled to 0° C. was quenched via the sequential addition of water (4 mL), 15% aq. NaOH (2 mL) Organics were extracted into a mixture of 3:1 DCM IPA (100 mL) and washed with water (50 mL) The organic layer was separated dried over MgSO4 Filtration concentration in vacuo

Conditions: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of acetic anhydride (10 mL, 106 mmol) and formic acid (30 mL, 795 mmol) was stirred at room temperature for 10 mins. 2-Chloro-3-fluoroaniline (2.9 g, 20 mmol) was added and the reaction mixture was stirred at 60° C. for 1.5 h. After cooling to room temperature, the solvents were removed in vacuo and the residue was redissolved in DCM (100 mL) and was washed with sat aq. NaHCO3 until the aqueous phase had a measured pH of 8. The organic layer was further washed with water (2×100 mL), separated and dried over MgSO4. Filtration and concentration in vacuo gave N-(2-chloro-3-fluoro-phenyl)-formamide (3.3 g, 95%) as a colorless solid which did not require further purification. MS (M+H)+: 173.9, tR=2.04 min (method 1). After cooling to room temperature the solvents were removed in vacuo the residue was redissolved in DCM (100 mL) was washed with sat aq.
