2,2-difluoro-N-methoxy-N-methylcyclopropane-1-carboxamide

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

Procedure: A solution of 2.00 g (12.1 mmol) of the compound from Example 120A in 20 ml of THF was added under argon to 2.87 g (13.3 mmol) of a 1N chlorophenylmagnesium bromide solution in diethyl ether in 20 ml of THF at RT, and the mixture was heated under reflux for 2 h. The reaction mixture was added to saturated aqueous ammonium chloride solution and extracted twice with diethyl ether, and the combined organic phases were dried over magnesium sulfate and concentrated. 2.47 g (94% of theory) of the title compound were obtained and were reacted without further purification. the mixture was heated under reflux for 2 h extracted twice with diethyl ether the combined organic phases were dried over magnesium sulfate concentrated

Procedure: 7.00 g (49.8 mmol) of 2,2-difluorocyclopropanecarbonyl chloride (described in the Journal of Fluorine Chemistry 1990, 49, 127-139) in 100 ml of dichloromethane were mixed with 6.32 g (64.8 mmol) of N,O-dimethylhydroxylamine hydrochloride and 18.1 ml (130 mmol) of triethylamine and stirred at RT overnight. Water was added to the reaction mixture, the phases were separated, and the aqueous phase was extracted twice with dichloromethane. The combined organic phases were dried over sodium sulfate and concentrated. 5.73 g (70% of theory) of the title compound were obtained and were reacted without further purification. the phases were separated the aqueous phase was extracted twice with dichloromethane The combined organic phases were dried over sodium sulfate concentrated
