J. Org. Chem. 1985, 50, 4484-4490 opaque prisms: mp 253.5-254 " C dec (sealed under argon);43 HPLC host/guest = 1.01.0. Anal. Calcd for C34H4$r14.4HClClJ18: C, 67.86; H, 6.73; N, 7.19. Found: C, 67.99; H , 6.77; N, 7.13. CP44*4HCl.(1,3-Dihydroxynaphthalene),. The crystalline complex was obtained by method A from 1.8 N HCl solution (host/guest = 1:2) as faint brown transparent needles which, after drying in vacuo a t 80 "C for 20 h, were characterized as CP44. 4HCl.(l,3-dihydro~ynaphthalene)
