Preparation of the intermediate phenylamide salt of formula 4B (base salt of the phenylamide compound of formula 4) consists of 8 steps, and stretching to the intermediate amide compound of formula 5A results in 9 steps. The manufacturing method described by Mr. Yamada is disclosed in Step 2.

この発明は、以下に記載する実例によって詳しく理解することができるが、但し、この発明は実例の範囲だけに限られるものではない。
式7のチロシン酸化合物(20.01g、110.4mmol)の水溶液(120ml)を無水酢酸(13.51g、132.4mmol)に加えた。4〜5時間加熱して回流後、蒸留法により該溶液を濃縮すると、淡い黄色の粘着性を具えた残留物が得られた。残留物はアセトン(80ml)で溶解して、未反応の式7のチロシン化合物をろ過により取り除いた。減圧により、ろ過による抽出物を濃縮し、残留物を再び酢酸エチル(100ml)で溶解し、水(50ml)で洗浄した。硫酸マグネシウムを乾燥し、減圧により濃縮して71%の収率のコロイド状の半固形の式15Aのフェニルアミドエステル化合物(17.62g、78.93mmol)を得た。 An aqueous solution (120 ml) of the tyrosine acid compound of formula 7 (20.01 g, 110.4 mmol) was added to acetic anhydride (13.51 g, 132.4 mmol). After heating for 4-5 hours and circulating, the solution was concentrated by distillation to obtain a light yellow sticky residue. The residue was dissolved with acetone (80 ml), and the unreacted tyrosine compound of formula 7 was removed by filtration. The extract by filtration was concentrated under reduced pressure, and the residue was dissolved again with ethyl acetate (100 ml) and washed with water (50 ml). Magnesium sulfate was dried and concentrated under reduced pressure to give a 71% yield of colloidal semi-solid phenylamide ester compound of formula 15A (17.62 g, 78.93 mmol).
