To
a
solution
of
methyl
2-(acetoxymethyl)nicotinate
(7.90
g,
37.76
mmol,
1.0
equiv),
in
MeOH
(80
mL)
was
added
acetyl
chloride
(3.60
g,
45.86
mmol,
1.2
equiv).
The
reaction
solution
was
stirred
overnight
at
room
temperature;
then,
the
solvent
was
removed
under
reduced
pressure,
and
the
resulting
residue
was
dissolved
in
water
(20
mL).
The
pH
was
adjusted
to
8
with
NaHCO
3
solid
and
extracted
with
ethyl
acetate
(30
mL*3).
The
combined
organic
phase
was
dried
over
anhydrous
sodium
sulfate
and
filtered,
and
the
filtrate
was
concentrated
in
vacuum.
The
residue
was
puri
-
fied
by
silica
gel
column
with
ethyl
acetate/petroleum
ether
(1/1),
giving
Methyl 2-(hydroxymethyl)nicotinate.
