実験手順
A mixture of N7-[(2S)-bicyclo[2.2.1]hept-2-yl]thieno[3,2-b]pyridine-6,7-diamine (0.060 g, 0.23 mmol) and 2-chloro-1,1,1-triethoxyethane (0.134 mL, 0.700 mmol) in acetic acid (0.2 mL) was stirred at 120° C. for 30 min. The solvent was removed and the resultant residue was dissolved in dichloromethane and purified on silica gel (eluting with 0-5% MeOH in dichloromethane) to give the desired product. LCMS calculated for C16H17ClN3S (M+H)+: m/z=318.1. Found: 318.0.
