Reaction Steps
Tert-butyl 2-(pyrrolidin-2-yl)acetate (1.00 g, 5.40 mmol) was added to a solution of methyl 6-chloro-5-nitronicotinate (1.169 g, 5.40 mmol) in THF (Volume: 10 ml). The reaction mixture was stirred at rt for 1 h and K2CO3 (0.760 g, 5.50 mmol) was added. The reaction mixture was stirred for 2 h and triethylamine (0.379 ml, 2.70 mmol) was added. The mixture was stirred for 1 h, filtered and concentrated in vacuo. Flash column chromatography on silica gel (120 g SiO2, hexanes:ethyl acetate 9:1) afforded methyl 6-(2-(2-tert-butoxy-2-oxoethyl)pyrrolidin-1-yl)-5-nitronicotinate (1.79 g, 4.90 mmol, 91% yield) as a yellow oil. [M+H] calc'd for C17H23N3O6, 365; found, 365.
