Procedure
A solution of 40% aq. methylamine (5 mL) and 2-methanesulfonyl-6-propyl-pyrimidine-4-carboxylic acid (150 mg, 0.614 mmol) is heated to 70° C. for 2 h. The reaction mixture is then evaporated and the crude compound is dissolved in 3N NaOH solution (10 mL). The aq. solution is washed with EtOAc (5 mL), is then adjusted to pH 3 with 25% aq. HCl and finally extracted with DCM (3×15 mL). The combined DCM extracts are dried over MgSO4, filtered and evaporated to give 2-methylamino-6-propyl-pyrimidine-4-carboxylic acid as a beige powder (128 mg); LC-MS: tR=0.56 min, [M+H]+=196.00.
