YieldReaction ConditionsOperation in experiment
46% With O-(benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium tetrafluoroborate; N-ethyl-N,N-diisopropylamine; In dichloromethane; at 20℃; for 49h;Cooling with ice; General procedure: To a 100 ml RBF, compound 6a (10 mmol), heterocyclic amine (2.18 g, 10 mmol) and TBTU (3.21 g, 10 mmol) and dry CH2Cl2 (15 ml) were taken and the contents of the flask were cooled in an ice-bath. DIPEA (8.9 ml, 50 mmol) was added drop wise to the flask over a 1-hr period. The reaction mixture became clear after complete addition. The ice-bath was removed and the reaction mixture was stirred at room temperature for 48 hrs. The white solid (precipitated out of the reaction mixture) was filtered and washed with water (20 ml). The crude products were directly recrystallised from boiling 1,4-dioxane.
