Procedure
The subtitle compound was prepared analogous to the method described in Example 19 (step 19d), starting from (S)-tert-butyl 1-(methoxy(methyl)amino)-1-oxopropan-2-ylcarbamate (1.86 g, 8 mmol) and a freshly prepared 2-Naphthylmagnesiumbromide 1M solution in THF (8 mL, 8 mmol). The obtained material was crystallised from Heptane. Yield 350 mg (14%).
