Mehtyl 6-[3-(1-adamanty)-4-methoxy phenyl]-2-naphthoate synthesis

10synthesis methods
-

Yield:106685-41-0 79%

Reaction Conditions:

in tetrahydrofuran;methanol at 0 - 20; for 1 h;

Steps:

1.5 Methyl 6-(3-(adamantan-l-yl)-4-methoxyphenyl)-2-naphthoate (5).
To a solution of adapalene (50 mg, 0.121 mmol) in 4: 1 THF/MeOH (0.4 mL) at 0 °C was added TMSCH2N2 (0.15 mL, 0.290 mmol) and the reaction was warmed to room temperature over 1 hour. The reaction mixture was concentrated, IN HCl was added, and was extracted with EtOAc 3x. The combined organic layers were washed with water and brine, dried over Na2S04, filtered, and concentrated; yielding the title compound as a white solid (41 mg, 79% yield).
