Procedure

A mixture of compound of example 101 (30 mg, 0.074 mmol), 2-tributylstannanyl oxazole (106 mg, 0.30 mmol), Pd(PPh3)4 (129 mg, 0.112 mmol) and dioxane (1 mL) in a sealed tube was heated at 120° C. for 15 h. The reaction mixture was diluted with MeOH, filtered through Celite and concentrated. The residue was purified by preparative HPLC to yield title compound (11.3 mg, 0.026 mmol, 39%) as a yellow oil.
