Versuchsvorschrift

4-Cyanobenzyl alcohol (150 mg, 1.13 mmol) in diethyl ether (10 mL) was treated with the product from Example 61A as an ethereal solution. The mixture was stirred for 2 hours, filtered, and the filter cake was washed with diethyl ether to provide the title compound as an off-white solid (150 mg, 44%). 1H NMR (300 MHz, DMSO-d6) δ 9.95 (s, 1H), 9.32 (d, J=1.0 Hz, 1H), 8.52 (d, J=6.1 Hz, 1H), 7.88-7.99 (m, 5H), 7.65-7.70 (m, 3H), 5.31 (s, 2H); MS (ESI+) m/z 304 (M+H)+.
