Procedure

To the above base, 1.2 g. (0.003 mol) in ether, a solution of 0.3 g. of oxalic acid in ether was added. The crude oxalate was recrystallized twice from ethanol to give 1.0 g. (68%) of (--)-3-phenoxy-N-[2-(2-furyl)ethyl]morphinan oxalate, m.p. 195°-197° (d), [α]D25 =-64.52° (c 1.03, MeOH).
