Participants

Reaction Steps

The title compound was prepared according to the procedure described in Example 127 following Step 6 and 7 by coupling of 3-chloro-4-(chloromethyl)-5-(4-methoxyphenyl)-1,2-thiazole and ethyl 3-(4-hydroxy-2,3-dimethylphenyl)propanoate followed by hydrolysis to afford the desired product as an off-white solid. 1H NMR: (300 MHz, CDCl3) δ: 7.502 (d, J=6.6 Hz, 2H), 7.00 (t, J=6.0 Hz, 3H), 6.784 (d, J=6.0 Hz, 1H), 4.925 (s, 2H), 3.87 (s, 3H), 2.99 (t, J=6.0 Hz, 2H), 2.64 (t, J=6.0 Hz, 2H), 2.27 (s, 3H), 2.18 (s, 3H). Mass spectrum (ESI, m/z): Calcd. for C22H22ClNO4S, 430.1 (M−H). found 430.1.
