1-(2-Chloro-1,1-dimethyl-ethyl)-3-(4-methyl-pyridin-3-yl)-urea (I-200d: 1 g, 4.149 mmol) in dry THF (5 mL) was added dropwise to a stirred mixture of NaH (298 mg, 6.208 mmol) in dry THF (10 mL) under argon atmosphere over a period of 10 minutes at 0° C. The resulting reaction mixture was stirred for 2 hrs. The reaction was monitored by TLC (5% MeOH in CHCl3). The reaction mixture was partitioned between water and ethylacetate. The organic layer was dried over Na2SO4 and concentrated to afford 800 mg of the product (94.33% yield).
