Procedure

The procedure used in Example 3: step b was followed using 3-iodo-4-methyl-N-(3-morpholin-4-yl-propyl)-benzamide ((Example 301: step a) 695 mg, 1.79 mmol), PdCl2(PPh3)2 (63 mg, 0.09 mmol), triethylamine (1.25 mL, 9.4 mmol), and 4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (0.91 mL, 6.4 mmol) in dioxane (5 mL). Analogous aqueous workup and purification by SiO2 flash column chromatography (0–10% MeOH in DCM) yielded the title compound contaminated with the product resulting from halide reduction (653 mg, 94%). The material was used without further purification.
