Procedure
The title compound was prepared following the general procedure 10, starting from 4-cyano-2-fluorobenzyl bromide (Fluorochem, 2.0 g, 9.3 mmol) and tert-butyl N-methyl-beta-alaninate (1.8 g, 11.2 mmol, prepared as described in Biorg. Med. Chem. (11) 2003, 3083-3099). It was isolated as a yellow oil (2.4 g, 87%). 1H NMR (CDCl3, 300 MHz) δ 7.82 (dd, J=10.0, 1.6 Hz, 1H), 7.69 (dd, J=7.8, 1.6 Hz, 1H), 7.60 (m, 1H), 3.58 (s, 2H), 2.61 (t, J=6.9 Hz, 2H), 2.38 (t, J=6.9 Hz, 2H), 2.14 (s, 3H), 1.38 (s, 9H). LC/MS (Method B): 293.0 (M+H)+. HPLC (Method A) Rt 2.44 min (Purity: 88.5%).
