Figure 4
A superposition of the mol­ecular conformations of erlotinib mol­ecules. The overlay was made by making a least-squares fit through the quinazoline ring system of erlotinib–EGFR kinase complex (V). The labels and r.m.s. deviations (Å) are as follows: erlotinib hydrate, (I)[link], 0.076; erlotinib hemioxalate, (II)[link], 0.087; erlotinib hemifumaric acid dihydrate, (III)[link], 0.07; erlotinib HCl, (IV), 0.076.
