Yield: 73%

Reaction Conditions:

with potassium carbonate in acetone

Steps:

1 Synthesis of N-(N-4-amidinobenzoyl-α,α-dimethyl-β-alanyl)-4-piperidineacetic acid STR7 (1) Methyl 2,2-dimethyl-cyanoacetate
EXAMPLE 1 Synthesis of N-(N-4-amidinobenzoyl-α,α-dimethyl-β-alanyl)-4-piperidineacetic acid STR7 (1) Methyl 2,2-dimethyl-cyanoacetate Methyl cyanoacetate (15 ml) and methyl iodide (200 g) were stirred and refluxed under the presence of potassium carbonate in acetone for 4 days and the potassuim carbonate was then removed by filtration. Acetone was distilled off from the filtrate and the residue was distilled in vacuo (16 mmHg, 76° C.) to yield methyl 2,2-dimethyl-cyanoacetate (19.5 g, 73%). NMR: ¹ H (270 MHz, CDCl₃) 1.62, s, 6H: 3.83, s, 3H: ¹³ C(67.5 MHz, CDCl₃) 24.6, 38.4, 121.0, 170.0
