실험 절차

(S)-2-(7-(3-Amino-3-methylbut-1-ynyl)-1-(4-chlorophenyl)-3-methylnaphthalen-2-yl)-2-tert-butoxyacetic acid (98) was prepared by the method of Example 67 using the reduction method of Example 51, step 3, for (S)-ethyl 2-(1-(4-chlorophenyl)-3-methyl-6-(trifluoromethylsulfonyloxy) naphthalen-2-yl)-2-hydroxyacetate instead of step 5, NaBH4 step, from ethyl 2-(7-bromo-1-(4-chlorophenyl)-3-methylnaphthalen-2-yl)-2-oxoacetate. The remainder of the sequence follows the method of Example 67 using 2-methylbut-3-yn-2-amine in Step 7. 1H-NMR: 400 MHz, (CD3OD) δ: 7.81 (d, J=8 Hz, 1H), 7.72 (s, 1H), 7.57 (m, 3H), 7.45 (d, J=8 Hz, 1H), 7.35 (s, 1H), 7.30 (d, J=8 Hz, 1H), 5.16 (s, 1H), 2.62 (s, 3H), 1.68 (s, 6H), 0.98 (s, 9H). LCMS-ESI+ (m/z): [M—NH2]calcd for C28H28ClO3: 447.2; found: 446.9.
