The solution was stirred at rt for 3 h. The reaction mixture was concentrated to afford product as an off-white solid (100%). 1H NMR (500 MHz, CD3OD): 7.01 (dd, J=8.8, 2.7, 2H), 6.61 (d, J=8.2, 2H), 4.63 (s, 0.5H), 4.41 (s, 0.5H), 3.63-3.53 (m, 4H), 3.35 (s, 3H), 3.28 (m, 0.5H), 3.19 (d, J=11.5, 0.5H), 2.91 (dd, J=10.3, 2.1, 0.5H), 2.82 (dd, J=10.2, 2.2, 0.5H), 2.67 (m, 1H), 1.94 (m, 1H), 1.76 (d, J=9.9, 0.5H), 1.66 (d, J=9.9, 0.5H).
