Yield: 90%
Reaction Conditions:
with sodium tetrahydroborate in methanol at 0; for 0.166667 h;
Steps:
130.130b
To a mixture of 5-methoxypicolinaldehyde (326mgs, 2.36mmol) in MeOH (10 mL) was added NaBH4 (71.9 mg, 1.90 mmol) at O0C. The mixture was stirred at O0C for 10 min after concentration in vacuo, the residue was purified with ISCO MPLC (40-80% EtOAc/hexane) to yield the title compound as a colorless oil (298 mg, 90 %). 1H NMR (CDCl3) 68.28 (d, 1 H), 7.09 - 7.27 (m, 2 H), 4.73 (s, 2 H), 3.89 (s, 3 H). MS (M+H+) = 140.
