2-Piperidino-ethylazide

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Compound 4-(prop-2-ynylamino)-6-(4-(tetrahydro-2H-pyran-4-yl)phenylamino)nicotinamide (Example 184) (20 mg, 0.057 mmol) was dissolved in 6 mL MeOH. To it were added 1-(2-azidoethyl)piperidine (18 mg, 0.11 mmol), DBU (26 μL, 0.17 mmol) and finally powder CuI (13 mg, 0.068 mmol). The mixture was stirred at RT for 5 h, filtered and subjected to reverse phase prep HPLC to isolate the title compound. MS found for C27H36N8O2 as (M+H)+ 505.4. UV: λ=259 nm. 1H NMR: (CD3OD) δ 8.14 (1H, s), 8.12 (1H, s), 7.39 (2H, dt, J=8.4; 2.0 Hz), 7.24 (2H, dt, J=8.4; 2.0 Hz), 6.20 (1H, s), 4.60 (2H, s), 4.05 (2H, m), 3.73 (2H, m), 3.59 (4H, m), 3.04 (2H, m), 2.87 (1H, m), 1.95 (2H, m), 1.86-1.75 (8H, m) ppm. filtered
