38. 2 (0.35 mmol), IMes·HCl (1; 0.35 mmol), and 8 mL of dioxane, and the mixture was heated at 100 °C. A solution of pentan-3-ol (35 mmol) in 4 mL of dioxane was then added dropwise, and the mixture was further heated for 1/2 h. The imine (7 mmol) in 4 mL of dioxane was then added dropwise, and the reaction was monitored by GC. After consumption of the starting material, the reaction mixture was cooled to room temperature and adsorbed onto silica. Purification was achieved by silica gel chromatography.
