Reaction Steps

To N-(tetrahydro-2H-pyran-2-yloxy) 2-{6-[(naphthalene-2-sulfonyl)-(2-pyrrolidin-1-ylethyl)amino]-3-azabicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxamide (0.234 g, 0.38 mmol) was added TFA:DCM:MeOH (6 ml, 1:1:1 mixture). The mixture was stirred for 3 h at r.t. and then concentrated in vacuo. The product was purified by reverse phase HPLC to yield the title compound (60 mg, 30%).
