实验步骤: A solution of 8.1 g (110 mmol) of n-butylamine and 8.6 g of butyrolactone in 50 ml toluene was allowed to reflux under nitrogen atmosphere for 50 hours. Volatile solvents were removed in vacuo. To a solution of 3.18 gm (20 mmol) of the resultant N-butyl 4-hydroxybutyramide in 50 ml of toluene were added 120 ml (120 mmol) DIBAL (25% W). The solution was heated with stirring at 70° C. for 18 hours. After cooling to 0° C., the reaction was quenched with methanol (⅓ amount of DIBAL solution was used) followed by addition of saturated solution of Rochelle's salt. The mixture was extracted twice with EtOAc; the organic extracts were washed with brine and dried over Na2SO4. to reflux under nitrogen atmosphere for 50 hours Volatile solvents were removed in vacuo The solution was heated After cooling to 0° C. the reaction was quenched with methanol (⅓ amount of DIBAL solution was used) followed by addition of saturated solution of Rochelle's salt The mixture was extracted twice with EtOAc the organic extracts were washed with brine dried over Na2SO4
