Procedure

The product of example 1 step c) (25.0 g), D-Alaninol (12.3 g) and diisopropylethylamine (26.0 g) were diluted in N-methylpyrrolidinone (250 ml) and stirred at 100° C. for 24 h before cooling and pouring the reaction mixture into H2O (2.5 l). The precipitate was filtered and dried in vacuo before being preabsorped onto silica gel. Chromatography using EtOAc. 4% MeOH/EtOAc as eluents afforded the desired product as a yellow solid (9.0 g. 32%).
