YieldReaction ConditionsOperation in experiment
With ammonia; In acetone; at 0℃; for 4h; General procedure: Various substituted BnCl 9a?k (2.5 mmol) and thiourea (0.19 g,2.5 mmol) were refluxed together in EtOH (2.5 mL) for 1 h. After removal of EtOH at reduced pressure, the obtained solid was slowly added to a mixture of NCS (1.33 g, 10 mmol), 2M HCl (0.68 mL) and MeCN (4 mL) over 30 min. After completion of the reaction, the MeCN was removed on a rotary evaporator. Then H2O (3 mL) was added, and the white solid was filtered and dried under an infrared lamp to afford10a?k (70percent?93percent), respectively, which did not require further purification.Then, 10a?k were treated with ammonia solution (1 mL) inacetone (2 mL) at 0 °C for 4 h. After removal of acetone at reduced pressure, the crude was extract with EtOAc, and the combined organic layers were washed with H2O, and brine. After drying over Na2SO4,filtering, and concentrating of the organic phase, the resulting yellow solid 11a?k was used directly in the next step. Finally, 11a?k and ethylchloroformate (1.2 eq) were refluxed together in the presence K2CO3(1.5 eq) in acetone (5.0 mL) for 4 h obtained 12a?k.
