実験手順

A solution of the product from step (iii) (0.2 g), L-prolinamide (0.062 g) and N,N-diisopropylethylamine (0.19 ml) in tetrahydrofuran (10 ml) was stirred at room temperature for 24 h. The solvent was removed, the residue dissolved in N,N-dimethylformamide (10 ml) and sodium cyanide (0.05 g) added and heated at 90° C. for 10 h. The mixture was partitioned between ethyl acetate and water, the organics dried (MgSO4) and evaporated under reduced pressure. The residue was purified by RPHPLC. Yield 0.062 g
