Participants

Reaction Steps

N-(α-Cyano-3-phenoxybenzyl)-N-methylpyrrolidinium methylsulfate (5) was prepared from α-(1-pyrrolidinyl)-3-phenoxybenzeneacetonitrile (Example 3) and dimethyl sulfate following essentially the same procedure as that described in Example 2. The product was obtained as a yellow oil. Proton magnetic resonance spectrum (CDCl3 ; ε in ppm): 2.4 (4H, m, pyrrolidine ring β-protons); 3.2 (4H, m, pyrrolidine ring α-protons); 3.2-3.8 (6H, m, N--CH3 and CH3SO4); 6.8 (1H, s, CH); 7.0-7.7 (9H, m, aromatic protons).
