Reaction Steps

The intermediate (S)-ethyl 3-(2-benzyl-4-(3-(cyclopentyloxy)-4-methoxyphenyl)piperazin-1-yl)-3-oxopropanoate (117 mg, 0.25 mmol) was dissolved in THF (4 mL) and treated with LiOH (12 mg, 0.5 mmol) in water (1 mL) and stirred for 24 h. The reaction mixture was evaporated to half-volume, diluted with water (5 mL) and the pH adjusted to pH ˜7 with a 1 N solution of hydrochloric acid. The resulting precipitate was filtered with the aid of water and air dried to afford the title compound as a solid (97 mg, 88%). LC/MS (Method A) 5.31 min, [M+1]+ 439.
