Sodium borohydride → HCID 22493824, compound

Participants

Reaction Steps

Aldehyde 102 is dissolved in methanol (150 mL). Sodium borohydride (3 g) is added in portions. After the addition was complete, the reaction is diluted with water and concentrated. The residue is dissolved in ethyl acetate, washed with brine, dried (Na2SO4) and concentrated. The product is purified by flash chromatography on silica gel (5% MeOH/CHCl3) to give 4.17 g of 103 as a cream colored solid. 1H-NMR (400 MHz, CDCl3): δ 0.79 (3H, t, d=7.4), 1.18 (2H, m, d=7.4), 1.60 (2H, m, d=7.6), 4.03 (2H, dd, d=7.6), 4.56 (2H, s), 6.84 (1H, s), 7.39–7.50 (3H, m),7.50–7.53 (2H, m).
