6.25 g (82%) | With sodium hydroxide; In 1-methyl-pyrrolidin-2-one; | Part (b) 2,6-Difluoropyridine-3-carboxaldehyde (4.89 g, 0.034 mole) was dissolved in 20 mL of N-methylpyrrolidone and chilled in an ice/water bath. N-methylpiperazine (3.5 g, 0.035 mole) was added dropwise and the reaction mixture was stirred for 15 minutes and then distributed between 5% NaOH and Et2 O. The organic phase was dried and concentrated to give 6.25 g (82%) of product. An analytical sample was obtained by recrystallization from pentane, mp 77-78 C. Analysis: Calculated for C11 H14 FN3 O: 59.18% C; 6.32% H; 18.82% N; Found: 58.97% C; 6.31% H; 18.95% N. |
