Procedure

4-(4-Hydroxy-phenyl)-tetrahydro-pyran-4-carbonitrile (1.29 g, 6.4 mmol), 2,2-dimethyl-3-pyrrolidin-1-yl-propan-1-ol (0.8 g, 5.1 mmol), PPh3 (1.67 g, 6.4 mmol), THF (16 ml) and DIAD (1.25 ml, 6.4 mmol) were reacted together according to general procedure H. The crude material was subjected to chromatography on silica eluting with DCM:MeOH (98:2). The resulting solid was slurried in TBME:heptanes (1:2, 1 ml) to provide the title compound (120 mg, 5%) as a white solid. 1H NMR (400 MHz, CDCl3), δ 7.37 (d, 2H), 6.94 (d, 2H), 4.12-4.03 (m, 2H), 3.89 (td, 2H), 3.71 (s, 2H), 2.57 (br s, 4H), 2.47 (s, 2H), 2.15-1.99 (m, 4H), 1.70 (brs, 4H), 1.00 (s, 6H).
