Reaction Steps

A mixture of 4,6-dichloro-2-(methoxymethyl)nicotinonitrile (75.7 mg, 0.349 mmol), (R)-1-(1-phenylethyl)urea (77 mg, 0.469 mmol) and Xantphos G2 (39 mg, 0.044 mmol) in THF (2 ml) was sealed, sparged with argon, charged with triethylamine (0.17 ml, 1.220 mmol) and heated to 50° C. for 17 hr. The mixture was cooled and filtered through celite, eluted with EtOAc before it was concentrated in vacuo and purified via flash chromatography (25-100% Et2O/hexane) to provide (R)-1-(4-chloro-5-cyano-6-(methoxymethyl)pyridin-2-yl)-3-(1-phenylethyl)urea. MS ESI calc'd for C17H18ClN4O2 [M+H]+ 345. found 345.
