Procedure

To a suspension of (R)-2-(3-(2-ethoxyphenoxy)piperidin-1-yl)pyrimidine-5-carboxylic acid (50 mg, 0.14 mmol) and HATU (63 mg, 0.17 mmol) in dry dichloromethane (3 mL) was added N,N-diisopropylethylamine (0.075 mL, 0.42 mmol) at 20-25° C. The mixture was stirred for 10 min, then methyl 3-(aminomethyl)-5-methoxybenzoate hydrochloride was added (33 mg, 0.14 mmol) at 20-25° C. The reaction mixture was stirred at 20-25° C. for 1 hour. The mixture was concentrated under reduced pressure and the resulting residue was dissolved in ethyl acetate (10 mL), washed with water (2 times with 10 mL), and dried over NaSO4. The organics were concentrated under reduced pressure to obtain methyl (R)-3-((2-(3-(2-ethoxyphenoxy)piperidin-1-yl)pyrimidine-5-carboxamido)methyl)-5-methoxybenzoate (65 mg, 87%).
