Yield:102390-36-3 81.5%
Reaction Conditions:
with water;sodium hydroxide in methanol at 20; for 1 h;
Steps:
192a.2; 192b.2 Step 2:
(1r,4r)-4-(dibenzylamino)cyclohexane-1-carboxylic acid
A solution of ethyl (1r,4r)-4-(dibenzylamino)cyclohexane-1-carboxylate (3.60 g, 10.24 mmol, 1 equiv), NaOH (0.82 g, 20.5 mmol, 2 equiv), H2O (15 mL) in MeOH (60 mL) was stirred for 1 h at RT.
The pH value of the solution was adjusted to 6 with HCl (0.1 M).
Then solids were collected by filtration and dried to afford the title compound (2.7 g, 81.5%) as a white solid. LCMS: [M+H]+ 324.15.
