Participants

Reaction Steps

1-Benzothiazol-6-yl-3-(2-chloro-1,1-dimethyl-ethyl)-urea (I-201a: 620 mg, 2.18 mmol) in dry THF (5 mL) was added dropwise to a stirred mixture of NaH (78 mg, 3.25 mmol) in dry THF (5 mL) under argon atmosphere over a period of 10 minutes at 0° C. The resulting reaction mixture was stirred at room temperature for 45 minutes. The reaction was monitored by TLC (5% MeOH in CHCl3). The reaction mixture was partitioned between chilled water and ethylacetate. The organic layer was dried over Na2SO4 and concentrated to afford 410 mg of the product (77.35% yield).
