Procedure:
To a solution of acetylsalicylic acid (1.6 g, 8.88 mmoles) in N,N′-dimethylformamide (20 ml) and under stirring, sodium ethylate (0.64 g, 8.88 mmoles) is added. After 30 minutes the obtained solution is added to a solution of 2,6-bis-(chloromethyl)pyridine (4.72 g, 26.81 mmoles) in N,N′-dimethylformamide (20 ml). The solution is left at room temperature for 7 days, under stirring, then it is diluted with ethyl ether and washed with water. The separated organic phases are anhydrified with sodium sulphate and the solvent is evaporated at reduced pressure. The reaction crude product is purified by chromatography on silica gel eluting with n-hexane/ethyl acetate 7/3. 1.7 g of the product are obtained as a yellow oil.

Procedure:
A 2 L 3-neck round bottom flask equipped with a condenser, internal temperature probe, was charged with (R)-ethyl 2-amino-5-methylcyclopent-1-enecarboxylate (185 g, 1093 mmol) and ammonium formate (103.4 g, 1640 mmol) in formamide (400 mL) and toluene (200 mL). The reaction was heated to an internal temperature of 150° C. and stirred for 36 hours. The reaction was cooled and transferred to a 2 L single next flask and excess formamide was removed by high vacuum distillation. The resulting oil was dissolved in CH2Cl2 and washed with brine. The combined aqueous layers were extracted with CH2Cl2. The combined organic layers were dried over sodium sulfate, filtered and concentrated to give the crude product as a brown semi solid which was taken into the next step without any further purification.
