実験手順

To a stirred suspension of 4-aminotetrahydropyran (123 mg, 1.2 mmol) in dioxane (5 mL) under argon at room temperature was added trimethylaluminium (0.6 mL of a 2M solution in toluene, 1.2 mmol). After 1 h, a solution of 4-methyl-2-[2-(5-methyl-3-phenyl-isoxazol-4-yl)-ethyl]-thiazole-5-carboxylic acid (100 mg, 0.3 mmol) in dioxane (5 mL) was added and the reaction mixture warmed to 90° C. After 3 h, the reaction mixture was cooled, quenched with ice water and extracted with dichloromethane. The combined extracts were washed with Seignette's salt solution then dried, filtered, and concentrated. Purification by chromatography (silica, 0 to 10% methanol in dichloromethane) gave the title compound (40 mg, 32%) as a colourless oil. MS: m/e=412.4 [M+H]+.
