실험 절차
Borontrifluoride diethyl etherate (16.51 g, 116.3 mmol) was added slowly to 3-chlorophenyl boronic acid (17.37 g, 111.0 mmol) in DCM (170 mL) at −5° C., while stirring. After 15 minutes, the title compound of Example 15.1 (37.71 g, 105.8 mmol) in DCM (150 mL) was added slowly. The reaction stirred for 1 h at 0° C. and sodium tetrafluoroborate (225 g in 300 mL water) was added and stirred for 1 h. The organic layer was separated, dried over sodium sulphate, filtered and concentrated and triturated with ether to afford the title product (31.6 g, 68%) as a light brown solid.
