Procedure
(S)-2-({(3S,8S)-3-[4-(3,4-Dichloro-benzyloxy)-phenyl]-2,3,6,7,8,9-hexahydro-[1,4]dioxino[2,3-g]isoquinoline-8-carbonyl}-amino)-3-[4-(2,3-dimethyl-pyridin-4-yl)-phenyl]-propionic acid methyl ester (20 mg) was reacted with 2-isocyanato-2-methyl-butane (prepared according to General Procedure AD) according to General Procedure I (with excess of isocyanate). The resulting compound was hydrolyzed according to General Procedure B to give the title compound (7 mg). LCMS (m/z): 852.
