H2O (1:1, 1.2 mL) was heated with stirring in a sealed tube
at 808C for 1.5 h. Then the mixture was poured into saturat-
ed NaHCO3, and the whole was extracted with AcOEt three
times. The combined organic layer was washed with saturat-

solvent, the resulting oil (0.179 g) was purified by silica gel
chromatography (hexane:AcOEt) to give pure 2,2-dimethyl-
dihydroquinoline (29) as an pale yellow oil; yield: 0.017 g
(42%).

[12] The highest yield (44%) of 15a was obtained from the
complex mixture by the reaction of 2-iodoaniline (17a)
in the presence of TPPTS (9) in H2O at 1008C for 3 h.

[14] It was reported that 2-iodo-N-allylaniline gave 3-meth-
ylindole (32) by intramolecular Heck reaction using
these conditions; a) R. Odle, ; B. Blevins; M. Ratcliff;

[15] When the crude product obtained just after work-up
was used, cyclized product (29) was formed in 22%
overall yield from 17a under similar reaction condi-
tions. To determine whether the Pd catalyst was deacti-
vated during the first step of the reaction, Pd(OAc)2
A
and TPPTS were further added to the mixture from the
first reaction, and then aqueous AcOH was added for
neutralization. However, the reaction did not proceed.
