Isoamylamine → HCID 58677374, compound

Participants

Reaction Steps

Combine 4-(5-Formyl-furan-2-yloxy)-benzamide (0.18 g, 0.78 mmol), isoamylamine (0.10 g, 0.1.17 mmol), 3 Å molecular sieves (2 g) in methanol (30 mL), agitate 18 hours at ambient temperature. Add sodium borohydride (0.058 g, 1.52 mmol), agitate 20 hours at ambient temperature. Filter through Celite, then concentrate in vacuo. Partition the residue between water (50 mL), and ethyl acetate (150 mL). Drain the organic layer, and dry over sodium sulfate. Purify via ISCO™ 100 c (40 g silica) using a gradient of 95:5:0.5 to 90:10:1 chloroform/ethanol/ammonium hydroxide to afford the title compound (0.160 g, 68%): mass spectrum (ion spray): m/z=303.18 (M+1); HPLC retention time: 5.79 min (HPLC method in this experiment: 5:95-95:5 ACN/0.1% TFA in water over 10 minutes using a 15 cm Zorbax column, running at 1 mL/minute, ultraviolet detector set at 254 nM).
