Yield	Reaction Conditions	Operation in experiment
98%		a) Preparation of Int. 23 A solution of 3-oxetanone (4 g; 55 mmol), trimethylsilylcyanide (5.46 g; 55 mmol) and Znl2 (0.010 g) in tert-butyl methyl ether (10 ml) was stirred overnight. Then 1- piperazinecarboxylic acid, 1,1-dimethylethyl ester, acetate (1 : 1) was added and the solution was further stirred overnight. The solvent was removed. The product was directly used as such for the next reaction step. Yield: 14 g of Int. 23 (98 %).

Yield	Reaction Conditions	Operation in experiment
51%	With potassium carbonate; In acetonitrile; at 20.0℃;	a) Preparation of Int. 62 A mixture of 1-piperazinecarboxylic acid, 1,1-dimethylethyl ester, acetate (1 : 1) (9.5 g; 50.8 mmol), 2-bromo-3-methoxy-propanoic acid, methyl ester (10.0 g; 50.8 mmol) and K2CO3 (10.5 g; 76.2 mmol) in ACN (150 ml) was stirred overnight at r.t.. Then the mixture was poured into water and extracted with EtOAc. The organic phase was washed with water, brine, dried over Na2S04 and evaporated in vacuum. The residue was purified by column chromatography over silica gel (eluent: DCM/EtOAc 1/1). The desired fractions were collected and the solvent was evaporated to afford 13.9 g of Int. 62 (51 %).
