실험 절차

In analogy to the procedure described in example 9.1, 2-(4-amino-3-fluoro-phenyl)-2-methyl-propionic acid methyl ester (Chung, Jae-Uk; Kim, Su Yeon; Lim, Ju-Ok; Choi, Hyun-Kyung; Kang, Sang-Uk; Yoon, Hae-Seok; Ryu, HyungChul; Kang, Dong Wook; Lee, Jeewoo; Kang, Bomi; Choi, Sun; Toth, Attila; Pearce, Larry V.; Pavlyukovets, Vladimir A.; Lundberg, Daniel J.; Blumberg, Peter M. Bioorganic & Medicinal Chemistry (2007), 15(18), 6043-6053) was reacted with triphosgene in the presence of Et3N in CH2Cl2 under reflux conditions for 16 h to give the title compound as brown oil which was used in the next step without further purification. MS: m/e=255.4 [M+NH4+].
