Reaction Steps

Similarly, N-Benzoyl-N′-[4-(2-methoxyethylformyl-amino)-cyclohexyl]methylthiourea was obtained: 100% yield, 378 (ESMS, MH+); 1H NMR (CDCl3) δ 10.85 (broad, 1H), 9.03 (broad, 1H), 8.18 & 8.08 (two s, 1H), 7.84 (d, 2H, J=7.9 Hz), 7.64 (m, 1H), 7.52 (d, 2H, J=7.8 Hz), 3.63-3.24 (m, 7H), 3.34 & 3.33 (two m, 3H), 2.03-1.13 (m, 9H). N-[4-(Isopropylformylamino)cyclohexyl]methylthiourea: K2CO3 (2 equivalents) in water was added to a solution of N-benzoyl-N′-[4-(isopropylformylamino)-cyclohexyl]methyl-thiourea in MeOH and stirred at room temperature overnight. The solvent was removed in vacuo and the residue was dissolved in EtOH. The solution was filtered to remove a white precipitate and the filtrate concentrated. The crude product was chromatographed to yield the desired product: 100% yield; 100% yield; 258 (ESMS, MH+); 1H NMR (CD3OD) δ 8.15 & 8.13 (two s, 1H), 4.15 & 3.73 (two m, 1H), 3.34 & 2.97 (two m, 1H), 3.29 (m, 2H), 1.26 (d, 3H, J=6.7 Hz), 1.23 (d, 3H, J=6.7 Hz), 1.91-1.03 (m, 9H).
