Procedure
NaOH (1N, 10 ml) was added to a solution of 4-(azetidine-1-carbonyl)-2-methyl-2H-pyrazole-3-carboxylic acid ethyl ester (1.32 g, 5.0 mmol) in THF (50 ml), and the mixture was stirred at r.t. (3.5 h). The mixture was neutralized by addition of HCl (1N, 10 ml). The mixture was evaporated under vacuum and the title compound, containing theoretically 2 equiv. of NaCl, (1.72 g, 99%) was used in Step 6 without further purification. MS (m/e)=210.2 [M+H+].
