Reaction Steps

Sodium triacetoxyborohydride (0.284 g) was added to N-cyclopropyl-3-fluoro-4-methyl-5-[3-{[(1R,2R)-2-methyl-3-oxo-1-phenylpropyl]amino}-2-oxopyrazin-1(2H)-yl]benzamide (Example 328e, 0.3 g), pyrrolidine (0.221 mL) and Hunig's Base (0.467 mL) in DCM (15 mL). The resulting suspension was stirred at 22° C. for 2 h. The reaction mixture was basified with satd sodium bicarbonate solution before extracting with DCM. The combined organic phases were concentrated in vacuo and the residue purified by preparative HPLC (Phenominex column using a 75-5% gradient of aqueous 0.2% ammonia in acetonitrile as eluent). The fractions containing the desired compound were evaporated to dryness to afford the title compound as a solid (0.046 g).
