Yield:1003639-36-8 86%
Reaction Conditions:
with trifluoroacetic acid in dichloromethane at 20; for 1 h;Temperature;
Steps:
8.1; 9.1 Step 1: Preparation of 2-(piperidin-4-yl) thiazole-4-carbaldehyde
To a solution of tert-butyl 4-(4-formylthiazol-2-yl) piperidine-1-carboxylate (0.5 g, 1.687 mol) in dichloromethane (10 ml), trifluoro acetic acid (5.20 ml , 67.5 mol) was added.The reaction mixture was stirred at room temperature for lb. The reaction mixture was concentrated under reduced pressure toobtain 2-(piperidin-4-yl) thiazole-4-carbaldehyde (0.285 g, 1.451 mmol, 86% yield). MS: m/z = 197.00 [M+1].
