実験手順

Ethyl-[2-chloro-3-nitro-6-(trifluoromethyl)-pyridin-4-yl]-benzylcarbamate (63 gm 160 mmol) was dissolved in tetrahydrofuran (300 mL) and to this was added 0.880 ammonia solution (100 mL) to give two phases. This was transferred to a pressure vessel, sealed and heated to 80° C. with stirring for 2 hours. The tetrahydrofuran was evaporated and the residue was partitioned between saturated brine and diethyl ether. The organic extracts were dried over sodium sulphate, filtered and evaporated to give a thick yellow slurry (65 gm) of crude product.
