Procedure

A mixture of 4-amino-2-[1-(3-ethoxy-4-methoxyphenyl)-3oxobutyl]isoindoline-1,3-dione (0.9 g, 2.34 mmol) and chloroacetyl chloride (0.29 g, 2.57 mmol) in tetrahydrofuran (20 mL) was heated to reflux for 10 minutes. The mixture was concentrated in vacuo to give 2-chloro-N-{2-[1-(3-ethoxy-4-methoxyphenyl)-3-oxobutyl]-1,3-dioxoisoindolin-4-yl}acetamide (1.07 g, 100%); 1H NMR (CDCl3) δ 10.56 (s, 1H), 8.71 (d, J=8.4 Hz, 1H), 7.66 (t, J=7.6 Hz, 1H), 7.53 (d, J=7.3 Hz, 1H), 7.09-7.05 (m, 2H), 6.82 (d, J=8.0 Hz, 1H), 5.75-5.69 (dd, J=5.3 and 9.8 Hz, 1H), 4.22 (s, 2H), 4.12 (q, J=7.1 Hz, 2H), 4.04-3.93 (m, 1H), 3.83 (s, 3H), 3.31-3.21 (dd, J=5.2 and 18.0 Hz, 1H), 2.18 (s, 3H), 1.45 (t, J=7.0 Hz, 3H).
