A mixture of (4-amino-2-chlorophenyl)(2-methylphenyl)methanone (61 mg. 0.25 mmol) (disclosed in WO 01/42189 A1), compound 436 (89 mg, 0.30 mmol), BINAP (5 mg), Pd2(dba)3 (5 mg) and Cs2CO3 (114 mg, 0.35 mmol) in 1,4-dioxane (5 ml) was heated to 120° C. under stirring for 3 days. The reaction mixture was filtered. The obtained solution was concentrated in vacuo. The residue was purified by chromatography (petroleum ether/ethyl acetate 1:1) to provide the desired product, which was not pure. The impure product was further purified by preparative TLC (petroleum ether/ethyl acetate 2:1) to give the pure title compound as brownish oil.
