tert-butyl N-[2-(4-aminophenyl)propan-2-yl]carbamate

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

实验步骤: Following general procedure C, (6-bromo-4-chloroquinolin-3-yl)(cyclopropyl)methanone (347 mg, 1.12 mmol) was reacted with tert-butyl 2-(4-aminophenyl)propan-2-ylcarbamate (420 mg, 1.68 mmol) to afford the desired product (422 mg, 63%) as a yellow solid: ESI MS m/z 524 [C27H30BrN3O3+H]+.

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

实验步骤: A pressure flask was charged with a suspension of tert-butyl 2-(4-nitrophenyl)propan-2-yl-carbamate (4.62 mmol) in ethanol (20 mL) and palladium on carbon (100 mg). The flask was placed on a Parr shaker, purged with H2 (30 psi), and stirred overnight. The crude product was filtered through celite, concentrated, and chromatographed (hexane:ethyl acetate) to obtain the desired product (420 mg, 36% over two steps) as an orange-red oil: 1H NMR (300 MHz, CDCl3) δ 7.26-7.17 (m, 2H), 6.67-6.62 (m, 2H), 4.82 (s, 1H), 1.60 (s, 3H), 1.57 (s, 3H), 1.37 (s, 9H). purged with H2 (30 psi) The crude product was filtered through celite, concentrated chromatographed (hexane:ethyl acetate)
