Reaction Steps

A mixture of 2-bromo-5-[2-(4-cyclobutylpiperazin-1-yl)-2-oxoethyl]-4,5,6,7-tetrahydro[1,3]thiazolo[5,4-c]pyridine (40 mg, 0.1 mmol), 3-methylsulfonyl-phenylboronic acid (40 mg, 0.2 mmol), Na2CO3 (42 mg, 0.4 mmol) and Pd(PPh3)4 (12 mg, 0.01 mmol) in DME (4 mL) and water (1 mL) is degassed with argon and heated at 110° C. in a sealed tube overnight. The mixture is cooled and the layers are separated. The aqueous layer is extracted with EtOAc (4 ml) and the combined extracts are dried and evaporated. The residue is purified by PTLC to give the title compound as a white solid. MS (M+1): 475.0; 1H NMR (δ, CDCl3): 8.44 (t, 1H), 8.15 (td, 1H), 7.94 (td, 1H), 7.62 (t, 1H), 3.86 (s, 2H), 3.65 (q, 4H), 3.46 (d, 2H), 3.09 (s, 2H), 2.97 (s, 3H), 2.68-2.78 (m, 1H), 2.33 (q, 4H), 1.62-2.07 (m, 6H).
