Reaction Conditions:
with Raney nickel in tetrahydrofuran at 60;Inert atmosphere;
Steps:
3.d Example 3
(D) Preparation of intermediate VI: In a hydrogenation reaction flask,43 g of ethyl 3- (4- (methylamino) -3-nitro-N- (pyridin-2-yl) benzamido) propanoateAnd 4.7 g of Raney nickel in 500 mL of tetrahydrofuran,Nitrogen replacement 3 times, and then into the hydrogen, stirring, heating to 60 ° C reaction,TLC monitoring reaction; the reaction was completed, suction filtration, washing the filter cake with a small amount of tetrahydrofuran; the filter cake was recovered and applied; the filtrate was dried over anhydrous sodium sulfate, filtered with suction and concentrated to dryness under reduced pressure to give 38.3g Intermediate VI (6), yield 96%
