实验步骤: 2-[N-(4-Chloro-phenyl)-hydrazino]-1-(methyl-piperidin-1-yl)-ethanone (0.75 g, 2.66 mmol) was dissolved in ethyl acetate (3 mL) and 4M hydrochloride in dioxane (0.7 mL) was added. The mixture was concentrated under reduced pressure to a glassy oil/foam. This was dissolved in a mixture of ethanol (4 mL) and water (2 mL) and heated to 60° C. The 4,4-diethoxy-N-methylbutan-1-amine (0.47 g, 2.68 mmol) was added and then heated to 7080° C. 28% aqueous HCl (0.35 mL, 2.66 mmol) was added and the reaction heated at 80° C. for 1 h. More 4,4-diethoxy-N-methylbutan-1-amine (0.2 g, 1.14 mmol) and 28% aqueous HCl (0.3 mL, 2.30 mmol) was added and heated for a further 3 h. Further 4,4-diethoxy-N-methylbutan-1-amine (0.3 g, 1.71 mmol) was added and heated for a further 6 h. The reaction was concentrated under reduced pressure to give a dark brown oil. The oil was subjected to column chromatography (silica gel, eluent: EtOAc:EtOH:NH4OH 7:3:1) to give a brown oil (0.29 g). Further purification of the brown oil by column chromatography (silica gel, eluent: EtOAc:EtOH:NH4OH 7:3:1) gave pure product (179 mg, 19%). The mixture was concentrated under reduced pressure to a glassy oil/foam This was dissolved in a mixture of ethanol (4 mL) and water (2 mL) heated to 7080° C the reaction heated at 80° C. for 1 h heated for a further 3 h heated for a further 6 h The reaction was concentrated under reduced pressure to give a dark brown oil
