Reaction Steps

A mixture of 3-bromo-5-(4-(4-methoxyphenethyl)piperazin-1-yl)-1,2,4-thiadiazole (55 mg, 143 μmol), 4,4-difluoropiperidine hydrochloride (67.8 mg, 430 μmol) and DIPEA (185 mg, 251 μl, 1.43 mmol) in N-Methyl-2-pyrrolidinone (1 mL) was heated with microwave at 200° C. for 2.5 h. The amber reaction solution was purified by preparative HPLC on reversed phase eluting with a gradient formed from acetonitrile, water and NEt3 to yield after evaporation of the product containing fractions 41.8 mg (69%) of the title compound as off-white solid. MS (m/e): 424.2 (MH+).
