Reaction Steps

Dissolve (S)-[1-(4-chloro-5-fluoropyrimidin-2-yl)-pyrrolidin-3-yl]-(2,4-dichlorobenzyl)-amine (318 mg, 0.84 mmol) in dry 1,2-dimethoxyethane (20 mL) and add dropwise sodium methoxide in methanol (25% w/v, 1.9 mL, 8.46 mmol). Stir at 70° C. overnight. Add aqueous 2 N hydrochloric acid to a pH of about 6-7 and extract with 30:70 isopropanol:chloroform. Combine the organic layers, wash with saturated aqueous sodium chloride, dry (magnesium sulphate), filter, and concentrate to give a residue. Chromatograph the residue on silica gel to give the title compound (130 mg, 41%). Dissolve the title compound in methanol and add 1 M hydrogen chloride in diethyl ether (350 μL, 0.35 mmol), triturate, and concentrate to give the hydrochloride salt of the title compound. 1H NMR (400 MHz, MeOH-d4) δ 7.96 (1H, s), 7.65-7.76 (2H, m), 7.51 (1H, dd, J=8.2, 1.6 Hz), 4.45-4.56 (2H, m), 4.17 (2H, d, J=6.4 Hz), 3.99-4.10 (2H, m), 3.85-3.95 (4H, m), 2.61 (1H, d, J=6.4 Hz), 2.39 (1H, d, J=6.1 Hz); MS (ES): m/z=371 [M+].
