1-Phthalimido-1-4′-methoxyphenyl)propane. To a stirred solution of 1-(4′-methoxyphenyl)propylamine (2.5 grams, 15.2 mmol) and sodium carbonate (1.74 grams, 16.4 mmol) in a mixture of water (50 milliliters) and acetonitrile (50 milliliters) was added N-carbethoxyphthalimide (3.34 grams, 15.2 mmol). The resulting suspension was stirred for 4.5 hours at room temperature, the acetonitrile was removed in vacuo and a solid formed. The slurry was filtered and the solid was washed with water and air dried to afford 1.73 grams (39%) of crude product as a white powder. The crude product was recrystallized from hexane/ethyl acetate and dried in vacuo (60° C., <1 mm) to afford 1.71 grams (38%) of the product as white crystals: mp 85-86° C.; 1H NMR (DMSO-d6) δ 7.92-7.79 (m, 4H), 7.46-7.28 (m, 2H), 6.97-6.83 (m, 2H), 5.19-5.06 (m, 1H), 3.72 (s, 3H), 2.56-2.13 (m, 2H), 0.87 (t, J=7.3 Hz, 3H); 13C NMR (DMSO-d6) δ 167.8, 1.5, 134.6, 131.7, 131.0, 128.6, 123.1, 113.7, 55.2, 54.9, 23.8, 11.3. Anal. Calculated for C18H17NO3. Theoretical: C, 73.20; H, 5.80; N, 4.74. Found: C, 73.24; H, 5.74, N, 4.86. HPLC 100%.
