Reaction Steps

To 3,5-bis(benzyloxy)isonicotinamide (1.6 g, 4.79 mmol) in THF (30 mL) was added Cp2ZrCl (3.7 g, 14.4 mmol, 3 eq.) at rt. The mixture was stirred at rt for 2 h, concentrated, and purified on silica gel using a mixture of EtOAc and hexanes as eluent to give 3,5-bis(benzyloxy)isonicotinaldehyde (580 mg, 38%) and (3,5-bis(benzyloxy)pyridin-4-yl)methanol (710 mg, 46%) as white solids. Data for aldehyde 1H NMR (400 MHz, CDCl3) δ 10.53 (s, 1H), 8.13 (s, 2H), 7.51-7.22 (m, 10H), 5.21 (s, 4H); LRMS (M+H+) m/z 320.1. Data for alcohol 1H NMR (400 MHz, CDCl3) δ 8.12 (s, 2H), 7.58-7.34 (m, 10H), 5.22 (s, 4H), 4.87 (s, 1H); LRMS (M+H) m/z 322.1.
