Vorschrift

After 2.5 hours in reaction, 0.625 g of N-Boc-3-pyrrolidinone, 0.91 g of D-glucose, 1.8 g of L-alanine, and 3.3 mg of pyridoxal phosphate were added. Further, after five hours in reaction, 0.625 g of N-Boc-3-pyrrolidinone, 0.91 g of D-glucose, and 3.3 mg of pyridoxal phosphate were added. Furthermore, after nine hours in reaction, 0.25 g of N-Boc-3-pyrrolidinone, 0.36 g of D-glucose, 19 mg of NAD+, and 3.3 mg of pyridoxal phosphate were added. During the reaction, the reaction liquid was sampled. From the sample, N-Boc-3-aminopyrrolidine was extracted by the addition of ethyl acetate after basifying the sample with 6 N aqueous solution of sodium hydroxide. The amount of N-Boc-3-aminopyrrolidine produced was measured by analyzing N-Boc-3-aminopyrrolidine under the following GC conditions. Further, by the law of the art, N-Boc-3-aminopyrrolidine thus obtained was acted on by 3,5-dinitrobenzyl chloride to form a dinitrobenzyl derivative. After that, the dinitrobenzyl derivative was analyzed under the following HPLC conditions, whereby the optical purity thereof was measured. In the result, the amount of N-Boc-3-aminopyrrolidine produced after 23 hours in reaction was 2.14 g. The absolute configuration of N-Boc-3-aminopyrrolidine was (S), and the optical purity was 99.4% e.e.
