实验步骤: Isopropyl iodide (2 equivalents) was added dropwise to a suspension of tert-butyl N-[4-aminocyclohexyl]methyl-carbamate (1 equivalent) and diisopropylethyl amine (3 equivalents) in THF. The resulting mixture was stirred for 1 day. TLC analysis showed some starting amine. Additional isopropyl iodide (1 equivalent) and diisopropylethyl amine (3 equivalents) were added to the reaction mixture and heated at 40° C. for 1 day. The reaction mixture was concentrated and chromatrographed to give tert-butyl N-[4-(isopropylamino)cyclohexyl]methylcarbamate: 22% yield, 271 (ESMS, MH+); 1H NMR (CDCl3) δ 4.65 (broad, 1H), 2.91 (m, 3H), 2.42 (m, 1H), 1.80 (ABm, 4H), 1.38 (s, 9H), 0.98 (d, 6H, J=6.3 Hz), 1.32-0.85 (m, 5H). The reaction mixture was concentrated

实验步骤: A solution of tert-butyl N-[(4-aminocyclohexyl)methyl]carbamate (4.683 g, 20.5 mmol) and benzoyl isothiocyanate (3.77 g, 23.1 mmol) in 180 ml THF was stirred at room temperature for 20 hours. The solvent was removed in vacuo to yield a golden viscous oil. The oil was triturated with 250 ml hexane and the resulting solid was collected by filtration and washed with hexane. The off-white solid was washed several times with hexane and was dried under vacuum to yield 91% (7.32 g) of the desired product as an off-white solid: 1H-NMR (CDCl3) δ 1.20 (6H, m), 1.44 (9H, s), 1.83 (2H, m), 2.25 (2H, m), 3.01 (2H, t, J=6.4 Hz), 4.20 (1H, m), 4.62 (1H, m), 7.51 (2H, t, J=7.9 Hz), 7.60 (1H, t, J=7.4 Hz), 7.81 (2H, d, J=7.2 Hz), 8.93 (1H, s); 392 (ESMS, MH+). The solvent was removed in vacuo to yield a golden viscous oil The oil was triturated with 250 ml hexane the resulting solid was collected by filtration washed with hexane The off-white solid was washed several times with hexane was dried under vacuum
