Procedure

104 mg 60% sodium hydrid was added to 700 mg 2-amino-4,5,7,8-tetrahydro-thiazolo (4,5-d) azepine-6-carboxylic acid tert-butyl ester in 1.5 mL THF at 0° C. Then, 162 μL methyliodide was dropped to the mixture. The reaction was stirred over night at RT. The solvent was removed and the residue was purified by HPLC and 121 mg of the desired product was obtained.
