実験手順: According to the general procedure A, 2-chlorotoluene (66 mg, 0.52 mmol) reacted with benzylamine (68 mg, 0.64 mmol) using 1 mol % of Pd(dba)2, 2 mol % of Ph5FcP(t-Bu)2, and sodium tert-butoxide (60 mg, 0.63 mmol) in toluene at 100° C. for 4 h to give the title compound (99 mg, 96%) as a solid after recrystallization from hexane: 1H-NMR (300 MHz, CDCl3): δ 7.48-7.35 (m, 5H), 7.14 (m, 2H), 6.75 (t, 1H, J=7.2 and 7.5 Hz), 6.68 (d, 1H, J=7.8 Hz), 4.44 (s, 2H), 3.93 (bs, 1H), 2.24 (s, 3H). 13C{1H}-NMR (100 MHz, CDCl3): δ 146.01, 139.46, 130.02, 128.62, 127.50, 127.20, 127.12, 121.86, 117.13, 109.93, 48.26, 17.52. GC/MS(EI): m/z 197 (M+), 120, 106. Anal. Calcd for C14H15N: C, 85.24; H, 7.66; N, 7.10. Found: C, 84.98; H, 7.64; N, 7.20. at 100° C. for 4 h

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 2-methylaniline (1.0 g) and triethylamine (0.95 g) in N,N-dimethylformamide (15 ml) was added benzyl bromide (1.9 g) at ambient temperature and the mixture was stirred at ambient temperature overnight. The reaction mixture was diluted with ethyl acetate and it was washed with water and brine. Drying, filtering and the removal of solvents afforded a crude product. The crude product was chromatographed on silica gel (n-hexane:ethyl acetate=10:1) to give N-benzyl-2-methylaniline (795 mg) as a slightly yellow oil. was washed with water and brine Drying filtering the removal of solvents afforded a crude product The crude product was chromatographed on silica gel (n-hexane:ethyl acetate=10:1)

実験手順: The general procedure under argon was followed using copper(I) iodide (19 mg, 0.10 mmol), K3PO4 (425 mg, 2.00 mmol), benzylamine (131 μL, 1.20 mmol), 2-iodotoluene (127 μl, 1.00 mmol), ethylene glycol (111 μL, 2.00 mmol) and 1-butanol (1.0 mL) at 100° C. Column chromatography using a solvent mixture (hexane/ethyl acetate=20/1, Rf=0.5) afforded N-(2-tolyl)benzylamine (136 mg, 69% isolated yield) as colorless liquid. The spectral data (1H NMR) matched with the literature references and GC analysis indicated >95% purity. See Maccarone, E.; Mamo, A.; Torre, M. J. Org. Chem. 1979, 44, 1143-1146. at 100° C
