Procedure: Reaction of 1-aminomethyl-cyclobutanecarboxylic acid methyl ester with cyclopentanone, sodium acetate and sodium triacetoxyborohydride in DCM gave 1-cyclopentylaminomethyl-cyclobutanecarboxylic acid methyl ester

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: After a mixture of 1-cyano-4-hydroxy-7-phenoxy-isoquinoline-3-carboxylic acid methyl ester (129 mg, 0.401 mmol), 1-aminomethyl-cyclobutanecarboxylic acid methyl ester (115 mg, 0.803 mmol in MeOH was microwaved at 150° C. for 500 min; cooled, concentrated, the residue was partitioned between EtOAc and diluted HCl solution, EtOAc phase was washed with water and diluted NaCl solution, dried over anhydrous sodium sulfate, filtered, concentrated and column purified to give product (172 mg). LC MS ESI+: 432 (M+1)+. was microwaved at 150° C. for 500 min cooled concentrated the residue was partitioned between EtOAc and diluted HCl solution, EtOAc phase was washed with water and diluted NaCl solution dried over anhydrous sodium sulfate filtered concentrated column purified

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 4-hydroxy-7-phenoxy-isoquinoline-3-carboxylic acid methyl ester (110 mg, 0.37 mmol) and 1-aminomethyl-cyclobutanecarboxylic acid methyl ester (159 mg, 1.11 mmol, available from Ukrorgsyntez Ltd) in MeOH (2 mL) was microwaved at 150° C. for 500 min; cooled, concentrated, the residue was partitioned between EtOAc and diluted HCl solution, EtOAc phase was washed with water and diluted NaCl solution, dried over anhydrous sodium sulfate, filtered, concentrated and column purified to give product (76 mg). LC MS ESI+: 407 (M+1)+. was microwaved at 150° C. for 500 min cooled concentrated the residue was partitioned between EtOAc and diluted HCl solution, EtOAc phase was washed with water and diluted NaCl solution dried over anhydrous sodium sulfate filtered concentrated column purified
