Benzyldiphenylamine → N,N-Diphenyl-1-naphthalenemethanamine

Participants

Reaction Steps

N-phenylnaphthaldimine (2.20 g, 0.010 mol) and benzylphenyl ether (1.84 g, 0.010 mol) were reacted as above for the preparation of benzyldiphenylamine. Aqueous work-up afforded a precipitate which was isolated by filtration and recrystallized from 95% ethanol to yield 2.3 g (74%) of needles, mp 170°-172° C. Anal. calcd. for C23H19N: C 89.28, H 6.19, N 4.53%; found: C 89.11, H 6.26, N 4.44%. 1H NMR (200 MHz, CDCl3) δ(assignment): 5.52 (s, 2H, CH2), 7.00-8.10 (m, 17H, aromatic). MS [m/e (70 ev, % of base peak)](C10H7)CH2N(C6H5)2 309 (M+., 4.8), 308 (M+--H., 29.0), 168 (M+--((C10H7)CH2)., 18.0), 141 (((C10H7)CH2)+., 100 ). FTIR (CDCl3): 3063, 3040, 1606, 1602, 1594, 1584, 1574, 1559, 1512, 1501, 1497, 1488, 1485, 1474, 1465, 1460, 1451 cm-1.
