Versuchsvorschrift
Using N-((5-chloro-2-methoxyphenyl)(cyano)methyl)tetrahydro-2H-pyran-4-carboxamide, the title compound was prepared following the synthetic procedures described for N-(2-amino-1-(5-chloro-2-methoxyphenyl)-2-oxoethyl)-3-(tert-butyldimethylsilyloxy)-3-methylbutanamide to give N-(2-amino-1-(5-chloro-2-methoxyphenyl)-2-oxoethyl)tetrahydro-2H-pyran-4-carboxamide as a white solid. LCMS (ESI) m+H=327.3; 1H NMR (400 MHz, DMSO-d6): δ 8.30 (d, br, 1H); 7.31-7.31 (m, 2H); 7.24 (s, br, 1H); 7.13 (s, br, 1H); 7.05-7.01 (d, 1H); 5.62 (d, 1H); 3.91-3.81 (m, 2H); 3.79 (s, 3H); 3.30-3.24 (m, 2H); 2.55-2.54 (m, 1H); 1.56-1.55 (m, 4H).
