Reaction Steps

To a stirred solution of N-[(4-{4-[(1-isopropylpiperidin-4-yl)oxy]phenyl}tetrahydro-2H-pyran-4-yl)methyl]-N-ethylamine (102 mg, 0.283 mmol) and triethylamine (99 μl. 0.708 mmol) in dichloromethane (1 ml) was added dropwise acetic anhydride (29 μl, 0.312 mmol). Reaction left at ambient temperature for 4 hours until reaction complete. Water (1 ml) and dichloromethane (10 ml) added to the reaction, the extracted with saturated NaHCO3 (2×10 ml). Organic washings were dried over Na2SO4 and concentrated in vacuo to give the title compound as an oil (107 mg, 94%). 1H NMR (400 MHz, CD3OD) δ 7.20-7.31 (multiplet due to rotamers, 2H), 6.92-7.00 (multiplet due to rotamers, 2H), 4.36-4.46 (m, 1H), 3.70-3.88 (m, 2H), 3.20-3.55 (several peaks due to rotamers, 4H), 2.78-2.90 (m, 3H), 2.60, (q, 2H), 2.25-2.52 (multiple peaks due to rotamers, 2H), 1.70-2.10 (multiple peaks, 11H), 1.10 (d, 6H), 0.80-1.00 (two triplets due to rotamers, 3H).
