実験手順

Methylamine (45.0 mg, 50 μl, 1.449 mmol) was added to a solution of 2-(2-(3-tert-butyl-4-formyl-1H-pyrazol-1-yl)acetamido)-N-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (100 mg, 0.248 mmol) and acetic acid (100 μl, 1.74 mmol) in DMF (1 mL). Sodium triacetoxyborohydride (527 mg, 2.484 mmol) was added and the reaction stirred for 17 h. The reaction was quenched with water (500 μl) and purified by preparative reverse phase HPLC. The clean fractions were passed down an SCX cartridge and eluted with 2M NH3 in MeOH. Volatiles were blown down under a nitrogen atmosphere to yield the title product (33 mg, 0.079 mmol, 32%).
