Procedure
Under argon, 0.82 g of benzyl [(2R)-3-hydroxybutan-2-yl]carbamate (Example 134A, 3.3 mmol, 1 equivalent) were reacted with 0.57 g of 1H-isoindole-1,3(2H)-dione (phthalimide, 3.9 mmol, 1.1 equivalents) and worked up analogously to Example 137A. This gave 1.25 g (72% of theory; purity 75%) of the title compound (diastereomer ratio about 3:1).
