Reaction Steps

A mixture of 3-[5-(2-chloro-ethylamino)-3H-isobenzofuran-1-ylidene]-1,3-dihydro-indol-2-one (1.10 g, 3.37 mmol) and piperidine (8 ml, 80.9 mmol) was heated at 110° C. for 4 hours. After cooled to room temperature, the mixture was poured into an ice water (150 ml) with stirring. The solid was filtered, washed with water and dried to give a crude product. Trituration of the crude product with CHCl3/hexanes afforded 3-[5-(2-piperidin-1-yl-ethylamino)-3H-isobenzofuran-1-ylidene]-1,3-dihydro-indol-2-one as a yellow solid (1.13 g, 89%).
