Reaction Conditions

Reaction Steps

NaBH4 (0.22 g, 5.82 mmol) was added to a solution of aldehyde 90 (0.776 g, 2.89 mmol) in MeOH (100 mL) at 0° C. The solution was stirred at 0° C. for 1 h, then quenched with brine and partitioned between EtOAc and water. Column chromatography of the organic portion on silica gel (eluting with 1:1 EtOAc/hexanes) gave {2-[4-(trifluoromethoxy)phenyl]-5-pyrimidinyl}methanol (91) (0.657 g, 84%) as a white solid: mp 84-85° C.; 1H NMR [(CD3)2SO] δ 8.86 (s, 2H), 8.50 (d, J=8.9 Hz, 2H), 7.51 (d, J=8.9 Hz, 2H), 5.46 (t, J=5.5 Hz, 1H), 4.60 (d, J=5.5 Hz, 2H). APCI MS m/z 271 [M+H]+.
