Reaction Steps
To a cooled suspension of lithium aluminium hydride (3.0 g, 79 mmol) in dry tetrahydrofuran (80 ml), concentrated sulfuric acid (3.87 g, 39.5 mmol) was added dropwise at a rate to maintain a temperature <12° C. The mixture was stirred at room temperature for 1.5 h. A solution of the above amide (12.8 g, 37.8 mmol) in dry tetrahydrofuran (80 ml) was added dropwise and stirring was continued for 2 h. The reaction was quenched by careful addition of ethyl acetate (100 ml) followed by water (5.7 ml). Filtration of the mixture and evaporation of the filtrate in vacuo afforded 2-chloro-12-(3-chloropropyl)-12H-dibenzo[d,g][1,3,6]dioxazocine as a foam.
