Procedure

To a solution of compound I (1 g, 2.21 mmol) in THF (10.0 mL), TEA (4 mL) was added followed by (PPh3)4Pd (0.25 g, 0.22 mmol) and CuI (42 mg, 0.22 mmol). The mixture was degassed using N2 for 30 min and TMS-acetylene (0.92 g, 6.64 mmol) was added. The mixture was heated in a microwave oven at 60° C. for 30 min. The reaction mixture was diluted with EtOAc (25 mL) and passed through a pad of celite. The filtrate was concentrated. Purification of the crude product provided 825 mg (80%) of compound J.
