Procedure
Ethyl 4-(4-(hydroxymethyl)phenoxy)butanoate 29b was prepared by reacting 4-(hydroxymethyl)phenol 27b with ethyl 4-bromobutyrate 28b according to protocol described for the compound 29a in Example 24 (Scheme 9). The ester 29b was isolated as colorless oil 96% yield (2.26 g). 1H NMR (400 MHz, CDCl3): δ 1.24 (3H, t, J=7.2 Hz); 2.07 (2H, m); 2.15 (2H, t, J=7.2 Hz)); 3.97 (2H, t, J=6.4 Hz); 4.10 (2H, q, J=7.2 Hz); 4.59 (2H, s); 6.88 (1H, s); 6.87 (1H, s); 7.24-7.27 (2H, m).
