Versuchsvorschrift

The title compound is prepared in analogy to Example 89 from Example 12 with (2R)-3-butanoyloxy-1,2-epoxypropane and subsequent hydrolysis of the butyrate with 1 equivalent of a 1M lithium hydroxide solution at 70° C. for 1 h. For the work-up the solvent is removed on a rotary evaporator, the residue is adjusted to a neutral pH using 1N hydrochloric acid and buffer pH 7 and extracted with dichloromethane. Purification takes place by RP-HPLC (Method 6).
