A mixture of crude {1-[4-(2-bromo-2-phenyl-acetyl)-phenyl]-cyclobutyl}-carbamic acid tert-butyl ester [Int-1-A] (1.26 g) and 4-methoxypyrimidin-2-ylamine (0.67 g) in DMF (21 mL) was heated overnight at 90° C. (bath temperature). On cooling the mixture was partitioned between EtOAc and water and the organic phase washed with brine, dried and concentrated to give a mixture of the title compound and Int-2-0. Purification was achieved by preparative HPLC to give the title compound.
