(S)-2-tert-butoxy-2-(5-(4-chlorophenyl)-2-((dimethylamino)methyl)-7-methylquinolin-6-yl)acetic acid → (S)-2-tert-butoxy-2-(5-(4-chlorophenyl)-7-methyl-2-(piperidin-1-ylmethyl)quinolin-6-yl)acetic acid

Participants

Reaction Steps

(S)-2-tert-Butoxy-2-(5-(4-chlorophenyl)-7-methyl-2-(piperidin-1-ylmethyl)quinolin-6-yl)acetic acid was prepared following the procedure used to prepare compound (S)-2-tert-butoxy-2-(5-(4-chlorophenyl)-2-((dimethylamino)methyl)-7-methylquinolin-6-yl)acetic acid (9) of Example 9, except that (S)-2-tert-butoxy-2-(5-(4-chlorophenyl)-7-methyl-2-(piperidin-1-ylmethyl)quinolin-6-yl)ethanol was used instead of (S)-2-tert-butoxy-2-(5-(4-chlorophenyl)-2-((dimethylamino)methyl)-7-methylquinolin-6-yl)ethanol. 1H-NMR 300 MHz, (CD3OD) δ 7.97 (s, 1H), 7.77 (d, 1H), 7.65-7.58 (m, 3H), 7.40-7.30 (m, 2H), 5.22 (s, 1H), 4.61 (s, 2H), 3.60-3.20 (m, 4H), 2.69 (s, 3H), 2.00-1.90 (m, 4H), 1.80-1.65 (m, 2H), 0.98 (s, 9H); LCMS-ESI+ (m/z): [M+H]+ calcd for C28H33ClN2O3: 482.0; Found: 481.3, 483.3.
