Reaction Steps

To a 12 L 3-neck round bottom flask was added isopropyl acetate (6.5 L). The solvent was cooled to 0° C. in an ice-water bath and 3-amino-1-propanol (1.14 Kg, 15.1 mol, 2.15 eq) was added in one portion. To this rapidly stirring solution, benzyl chloroformate (1.20 Kg, 7.03 mol, 1.0 eq) was added dropwise over 2h while maintaining the internal temperature of the flask between 10° C. and 15° C. After the addition was complete, the reaction mixture was allowed to stir between 10° C. and 15° C. for an additional 0.3 h after which time water (3.5 L) was added in one portion. The solution was then partitioned and washed with an additional 2×3.5 L of water. The organic layer was dried over potassium carbonate and concentrated to give a solid that was dissolved in excess isopropyl acetate and precipitated from solution by adding the compound to heptane. The solid was filtered under nitrogen to yield 1.20 Kg (82%) of the desired product as a colorless solid.
