Sodium borohydride → 6-(1-Hydroxy-indan-5-yloxy)-nicotinamide

Participants

Reaction Steps

Using a method similar to intermediate 13, using 6-(1-Oxo-indan-5-yloxy)-nicotinamide (Intermediate 4, 500 mg, 1.86 mmol) and NaBH4 (105 mg, 2.79 mmol) gives 6-(1-Hydroxy-indan-5-yloxy)-nicotinamide (346 mg) as a white solid. Mass spectrum (ion spray): m/z=271 (M+1); 1HNMR (DMSO-d6): 8.58 (s, 1H), 8.22 (d, 1H), 8.00 (s, 1H), 7.45 (s, 1H), 7.34 (d, 1H), 7.03 (d, 1H), 6.97 (s, 1H), 6.93 (d, 1H), 5.03 (t, 1H), 2.93-2.86 (m, 1H), 2.73-2.66 (m, 1H), 2.38-2.30 (m, 1H), 1.84-1.72 (m, 1H), 1.33 (s, 1H). Convert 6-(1-Hydroxy-indan-5-yloxy)-nicotinamide to the title compound using a method similar to intermediate 13. Due to instability, use this material without purification.
