実験手順

(3S)-3-(3,4-dichlorophenyl)-4-(5-phenyltetrazol-1-yl)-butyraldehyde (0.90 g) in methanol (6 mL) and dichloromethane (2 mL) was added to a solution of 1-(piperidin-4-yl)tetrahydropyrimidin-2-one (0.458 g) and acetic acid (0.14 mL) in methanol (5 mL). After 40 minutes, sodium cyanoborohydride (0.157 g) in methanol (5 mL) was added in a single portion. After being stirred for 2 hours, the reaction mixture was diluted with aqueous sodium bicarbonate, stirred for 30 minutes, and extracted with dichloromethane. The organic extracts were dried, evaporated, and chromatographed, with dichloromethane:methanol (gradient 98:2, 70:30) as eluent. The purified material was dissolved in dichloromethane, precipitated out as the hydrochloride salt with ethereal hydrogen chloride, evaporated, and placed under high vacuum overnight to give the title compound as a white solid (0.928 g); NMR (CD3OD): 7.61-7.47 (m,3), 7.30 (m,2), 7.21 (d,1, J=8.2), 7.03 (d,1, J=2.1), 6.75 (dd,1, J=2.1, 3.3), 4.94 (dd,1, J=4.8, 14.2), 4.74 (dd,1, J=9.4, 14.2), 4.34 (m,1), 3.58 (m,2), 3.25 (m,5), 3.15-2.98 (m,3), 2.76 (m,1), 2.33-2.11 (m,4), 1.90 (m,4); MS: m/z=528(M+1). Analysis for C26H31Cl2N7O.0.15 Et2O.2.50 HCl: Calculated: C, 50.65; H, 5.59; N, 15.54; Found: C, 50.58; H, 5.61; N, 15.27.
