Reaction Steps

The title compound was prepared starting from 2-(3-pyridyloxy)ethanol (from Example 150, Step 1) and 3-chloro-2-[4-tert-butoxycarbonyl-(2R)-methyl-1-piperazinyl]pyrazine (from Example 172, Step 2). The pure free base was precipitated as its hydrochloride salt with HCl/ether to give the title compound as white crystals: yield 31%; mp 180-183° C.; HRMS m/z calcd for C16H21N5O2 (M)+ 315.1695, found 315.1689. Anal. (C16H21N5O2.1.33HCl) C, H, N.
