Procedure

A solution of 1-(t-butoxycarbonyl)-4-(1,3-diethyl-4-methyl-(1H)-pyrazol-5-yl)piperidine (348 mg) (from Step E) in 2.5 N HCl in methanol was stirred at rt for 16 h. The solution was concentrated and the resulting solid was suspended in ethyl acetate, filtered and dried to afford 293 mg (92%) of the title compound.
