YieldReaction ConditionsOperation in experiment
84.9% To a reactor equipped with, over head stirrer, reflux condenser, nitrogen bubbler, dropping funnel and thermo-pocket, was charged <strong>[14472-80-1]4-(4-chlorophenyl)cyclohexanone</strong> ( 85.0 g, 0.41 mol) under a positive nitrogen pressure at 25 °C. Freshly dried dichloromethane (850 mL) was added to dissolve the material and the reaction mass was cooled to -35 °C. A 1 molar solution of titanium tetrachloride (85.4 g, 0.45 mol) in dry dichloromethane (550 mL) was added drop wise to the reaction mass. After compete addition of titanium tetrachloride reaction mixture was warmed to 0 °C and stirred for 1 h. Reaction mass was again cooled to - 55°C and at this temperature, a solution of (l,2-dihydronaphthalen-4-yloxy)trimethylsilane (11 1.3 g, 0.515 mol) in dichloromethane (1 L) was added and allowed to stir at -55 °C for lh. After which, again reaction mixture was warmed to 0°C and then quenched with ice water (2500 mL) under vigorous stirring and diluted with dichloromethane (3000 mL). Organic layer was separated and washed with saturated sodium bicarbonate solution (500 mL) and brine. After stripping off the DCM layer under reduced pressure, the residue was suspended in ethyl acetate (300 mL) and resultant slurry was refluxed for lh and cooled to RT. Resultant solid were filtered off to give the product as off-white solid. (122.3 g, 84.9 percent yield). Generally yield of the product ranges from 78 to 85 percent.FTIR (neat): 3441, 2945, 2927, 2858, 1654, 1598, 1397, 1230, 1046, 962, 840, 751, 610 cm"1. 1H NMR (CDCb, 400 MHz): delta 1.55(t, IH), 1.68-1.79 (m, 4H), 1.91-2.02 (m, 2H), 2.04-2.1 1 (m,2H), 2.32-2.36 (dd, IH), 2.45 (t, IH), 2.68 (dd, IH), 3.05(d, 2H), 4.98 (s, IH (OH)), 7.20- 7.37 (m, 6H), 7.52 (t,lH), 8.04 (d,lH); ,3C NMR (CDC13, 100 MHz): delta 25.5, 28.6, 28.9, 29.5, 32.0, 35.7, 43.6, 57.1, 72.8, 126.8, 127.5, 128.3, 128.4, 128.5, 131.4, 133.1, 133.9, 144.2, 145.7, 202.8; MS (EI): C22H23C102 : 354.86; [M]+: 355.85; DSC peak at 167.85 °C (10°C/min)PXRD [20] (Cu Ka. = 1.54060 A, = 1.54443 A, Kp = 1.39225 A; 40 mA, 45 kV): 8.07, 8.81, 8.93, 9.76, 10.51, 15.60, 17.29, 17.44, 19.10, 19.32, 20.84, 22.96, 24.37, 27.96, 29.55,
