Procedure

To a stirred mixture of 2-amino-5-(S)-aminomethyl-6-(1-(S)-phenyl-ethyl)-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine-3-carboxylic acid tert-butyl ester (0.24 g, 0.67 mmol) in acetonitrile (30 ml) was added N,N-diisopropylethylamine (0.16 ml, 0.93 mmol) under nitrogen. 2-Bromo-methyl-3-methoxymethoxy-benzoic acid methyl ester (0.16 g, 0.55 mmol) dissolved in acetonitrile, was added via syringe pump at a rate of 0.3 ml/hour. Once the addition was complete, the reaction mixture was stirred at room temperature for 24 hours. Tlc analysis (1:1 ethyl acetate/hexanes) indicated the reaction to be complete. The volatiles were removed in vacuo and the resultant oil dissolved in ethyl acetate/water. The layers were separated and the aqueous layer extracted with ethyl acetate (3×). The organic layers were combined, dried (MgSO4), filtered and the solvent evaporated in vacuo, which afforded 0.34 g (100%) of 2-amino-5-(S)-(4-methoxymethoxy-1-oxo-1,3-dihydro-isoindol-2-ylmethyl)-6-(1-(S)-phenyl-ethyl)-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine-3-carboxylic acid tert-butyl ester, which was used without further purification in the next step.
