Participants

Reaction Steps

7-Methyl-5-piperidin-4-ylmethyl-2-(4-trifluoromethoxy-benzyl)-2,3-dihydro-isoindol-1-one (50.0 mg, 0.124 mmol) was dissolved in methanol (0.2 mL) and acetic acid (0.2 mL) and 37% formaldehyde (0.2 mL) was added at room temperature. The mixture was stirred for ten minutes and sodium cyanoborohydride (1M in THF, 0.2 mL, 0.20 mmol) was added and the mixture was allowed to stir overnight at room temperature. The reaction was diluted with dichloromethane, washed with sodium bicarbonate (sat) and brine dried over sodium sulphate, filtered and concentrated. Column chromatography provided the title compound as an off white foam (23.8 mg, 44%). 1H NMR (300 MHz, CDCl3): δ 7.37 (d, 2H), 7.21 (d, 2H), 6.99 (d, 2H), 4.77 (s, 2H), 4.22 (s, 2H), 2.91 (d, 1H), 2.77 (m, 4H), 2.58 (d, 2H), 2.30 (m, 3H), 1.99 (m, 1H), 1.67-1.27 (m, 6H).
