A mixture of (3-iodo-benzyl)-carbamic acid tert-butyl ester (272 mg, 0.816 mmol), 4-(2-aminoethyl)morpholine (0.16 mL, 1.225 mmol), K2CO3 (232 mg, 1.679 mmol), CuI (19 mg, 0.10 mmol), L-proline (19 mg, 0.163 mmol) and DMSO (5 mL) was heated at 85° C. for 1 h. The reaction was cooled, poured onto water and the aqueous layer extracted with EtOAc (×3). The organic layers were combined and washed with water, brine and dried (Na2SO4). Chromatography (MeOH/EtOAc) afforded [3-(2-morpholin-4-yl-ethylamino)-benzyl]-carbamic acid isopropyl ester (200 mg) as an orange viscous oil. m/z (M+1) 336.16.
